I brewed for years in a system that was almost entirely plastic (though I always fermented in glass carboys). Since I am starting from scratch, I've been looking for something easier to clean & maintain with less risk of getting an infected batch, especially since I may be upgrading to 10-15 gallon batches (to get more out of the occasional brewday).
Not sure I'm sold on RIMS, though the concept looks cool. I was looking at BrewMagic systems before I settled on Blichmann (you want to talk $$$ go look at a Sabco BrewMagic. It'll curl your hair!)
And kegging is absolutely a must. If I want or need to bottle, I'll use a counterpressure bottler to do it. No more bottle-conditioning for me, unless there's a good, compelling reason to do so and even then, I'll probably only bottle-condition a portion of the batch and keg the rest.
Interestingly, the one piece of hardware I held onto is my beer engine. It's an Angram and from the look of the wooden base, it actually spent time in a pub somewhere in the UK. I also have a 3-gallon corny keg with a shortened tube that I use to "cask-condition" my English ales so that I can get as close to the Real Ale experience as a Yank can.
