I dont know the retailer, but you could use the search box to look for threads about them (top right of the screen), dovo blades are meant to be pretty good, again no specific experience, but they are one of the 3 or 4 recommened new production manufacturers, there was a thread discussing how honed the royal shave blades are, but i cant recall the outcome, you could always email them to ask if the blades are factory honed or honed on site.
The omega cream is very nice in my opinion, in fact i was thinking the other day that i could just use it ongoing, but realistically i will want to try other stuff
Have you looked at straight razor designs? they have their blades honed by lynn if i recall so they will definately be shave ready, again i havent tried their product but they invariably get stellar reviews. i believe they also sell the ralf aust line, which are supposed to at least compare to dovo, and their modular strops seem to be pretty good value considering that you are able to get a large range of replacement strop materials for relatively low prices.
The other alternative is to buy the various things you want in a non kit form, and look for a nice vintage razor.
A SRD modular strop (i have even heard guys recommned just buying the pads for the paddle strop and making your own base to save a bit of cash) is about $90, the omega is about $10 if i recall, if you dont mind boar brushes you can get a semogue 1305 for about $15, a lather bowl can be made from a continental coffee cup ( a couple of dollars if you shop around)or just a small bowl from your cupboard (free), and that still leaves $95 to pick up a razor (or more if you just buy the leather (and fabric) component(s). you should be able to get a reasonably nice vintage from the SRP classifieds for that, or a new razor even.
