At an abstract level, very little has changed in my opinion. There have always been certain brands that were popular, and therefore, relatively expensive. When I started, everyone wanted W&B razors, so they went for USD 150 while regular razors were still USD 50 or less. Filarmonicas could still be had for USD 50, which was a reasonable price. Dubl Ducks, possibly the most common razors in the market, also fetched relatively steep prices, much to the amusement of the men who had made them. Hones? First, everyone had to have a full set of Nortons (I still have one...). Then Naniwas. Lapping films. Diamond pastes. Natural hone crazes came and went. Strops? There even were strop progressions. A craze which did not last long after the vendor who invented it was banned...
So, nothing new in the hardware department, really. Only, prices have risen, and then dropped again somewhat. You will still find the occasional person with more money than sense forking out four digit sums of money for some shiny toy on eBay, but as long as it makes these people happy, why bother?
eBay has become very much unusable. I quite like this eBay Purchasing Primer, but too few people seem to read it. eBay is full of broken trash, shoddily "restored" (rather, raped) trash, and overpriced trash. There are also new old stock razors, but typically at absurd prices given their complete lack of rarity (hint: if you want a rare razor, get a Desert Rider).
The "custom scale" madness seems to have abated, thank God. A few years back, too many people seemed eager to rip perfectly salvageable scales off vintage razors, only to replace them with recycled glow-in-the-dark bowling balls. And Jesus wept. These days, the punters seem to have learned to appreciate the beauty of original designs more, resulting in a slew of skilfully executed "original restores" (aka restorations). I like that a lot, because unlike NOS blanks, NOS scales are very hard to come by.
The one area where I actually see a lot of movement, is soaps (and, to a lesser degree, creams). When I started, you either went for supermarket brands, invested a bit more in English products, or bought Castle Forbes. And that was that. With the advent of online shaving stores came more products, yet most still industrially made.
I have always had a soft spot for interesting software. Meaning, innovative, unusual, or simply rare. Otoko shaving soap being a good example. Affordable, completely out of the ordinary, yet functional. Not the best shaving soap ever made, but made by an individual who is dedicated to the point of drivenness, functional in an unobtrusive, understated way, and ethically soundly marketed.
At the other end of the spectrum, I have seen the rise of products which are touted as "artisan", but seem to be made from cheap import base products to all intents and purposes. Scents are the latest craze, and the ones I had the distinct displeasure of sampling were atrocious. The olfactory equivalent of pink candy stripe swirl custom scales. Of course there is a market for such monstrosities. Just like there are markets for Brazilian animal porn, American beer, or German romantic novels. But that does not mean I have to enter them.
That said, if you keep an open, but focused, mind, getting interesting, innovative quality equipment has never been easier. Once you understand how marketing works in the shaving scene (vendors and manufacturers subverting entire online communities; reviews being rigged; blogs and vlogs begin leveraged for viral marketing in dark grey areas), you will be fine. Never better, really. I think that is great. Overall, and despite some fairly ugly developments in niche markets, the shaving scene has become far more vivid, exciting, and enjoyable.
Good stuff.
PS On a personal note, one thing has not changed, and I find that very, very sad. No real effort at collating information available in one central place has been made. The Wiki/Library here is in a state of almost complete neglect. The Straight Razor Database a few people here built never really took off, either. I have, quite honestly, given up hope that this will ever change. The Google Arts Project would be a good place to replicate the SRDB, but I am not going to spend a few hundred hours of my time again to no avail :)
