I develop my own B&W using a darkbag. Never done prints, if I had space and time to spare I'd definitely do some prints, but I suspect that i would only do a few before reverting to getting a good lab to do them instead, to be honest. Dev is easy, prints more time consuming...
But if you had a room that could be blacked (temporarily) out then why not? I did look into being able to light seal my bathroom, so if i wanted to print I could, but there just isn't enough space in there. I looked on ebay for an enlarger, and it looks like you can get the kit reasonably cheaply. As with film cameras, I suspect you could get the equipment and later possibly sell it on for no real loss.
I also saw a 'portable' dark room - basically a vary vary large dark bag concept, which I am interested in. That isn't overly cheap (around £600 from memory), and space is still an issue. Plus I can't imagine what the heat would be like trying to use it in summer.
