I'm looking for something I can take for long distance travel - interstate. However, my means are quite limited, on the low-end-used to craigslist level. Also, I'm 6'4", 280, with a very long torso. A 23" with handle bars extended forward wasn't long enough for me. I've been told I need at least a 25" top tube, which seems quite uncommon, much less finding one at my price-point. Maybe it would be better to just try and find a frame, and then bargain hunt for the rest of the bike? And it makes it hard to find something on craigslist when I have no earthly idea which brands are good and which are lousy, or any other things I need to take into consideration. Knowing which brands are (the bike versions of) Hyundais and which are BMWs should at least help a little.
