One thing that concerns me is that although I'm pretty short (5'2'') I have a really long torso and short legs-it's been a little challenging to get a bike to fit.
I have the same issue, except that I'm a little taller (5'4"ish). After trying out a lot of different bikes, I ended up with a LeMond--the Reno...partly price (I wanted to keep the sticker price under a thousand) and partly the color scheme. It was the one whose geometry seemed to work the best for me, because in most of the other ones finding a long enough top tube to accomodate my torso length and reach started pushing me into sketchy territory on standover height. Ultimately, I chose the bike that was the most comfortable straight off the shop floor and just accepted that there would probably need to be some tweaks done along the way to make it "right"...it was also the bike I had the most fun on during my test ride, taking it *much* further than the rest of them without even realizing it because it just felt better, so I wasn't fidgeting as much on it trying to find a comfortable position for my arms.

Then again, I've only had the bike for a week, so I don't really know anything. LOL.
