I got my straight razor at a local cutlery shop, a lower end model for $40. Strop was about $12, and brush was an xmas gift (I believe retails around $50). Not cheap, but I always get a great shave from it.
This isn't for one of those quick shaves before work, though. It'll take at least 10 minutes including lathering and shaving (longer if you do a second run against the grain). I get best results after a hot shower, though keeping the mirror clear is quite annoying.
If you want the feel of the straight without the honing/maintenance, as well as want a cheaper alternative, Dovo makes straight razors with disposable blades. I think replacement blades run from $5 to $8, depending on size and manufacturer.
