I'm 6'6'' so it's difficult to find larger frames, but luckily the guitar player in my band has a workshop and was able to get his hands on one large enough for me. I pieced the bike together for me and charged me 40 bucks. I'm fairly sure I could have done it myself, but it was nice to learn everything from someone who's been riding and building bikes forever.
If I could make a suggestion, I would just hit up garage sales, craiglist, and other local means. You can find quality bikes for cheap and then just make changes if you end up liking riding. No point in buying a Lambo if you just started driving...unless that's how your livin?
I found an early 80's Raleigh Record Ace at a garage sale early this summer for 15 bucks. It has a fairly rare plastic Brooks saddle, which is what caught my attention..and the frame is nice and large. Haven't done much with it yet, but some tear down and cleaning up. Don't have much use for multi speed bikes, so I'll probably strip it down and make it a little more simple.
Here's someone selling the same bike on ebay -
