Hey guys, I just joined and this is my first post.

I'm looking to buy a road bike to ride it around town when I need to make small errands: visits to my parents house, quick grocery strips, etc. I've never had a road bike, and I haven't had a bike in years! I want to try out a road bike this time, and I'm looking on Craigslist mostly.. I have a question regarding the standover height and road bike size.

I'm 6', but my inseam is only 32". I looked at a few different bike size charts, they have some variations on size recommendations. Anyway, this is not clear to me; should my inseam be greater than the standover height? Is it hazardous if my inseam is shorter? How about bike size? What do you guys think will be ideal for me (shorter legs, longer torso)? I have some back problems, so my doctor advised me to lower the seat as much as possible to keep my back straight, so I'm thinking reaching the pedals won't be a problem. I'm just not sure what a proper bike size is.

I'm looking at a Trek 1200 in CL, and its size is 60cm with standover height of 33.5". Any inputs are appreciated. It's hard to find decent used bikes (or I just don't look frequently enough?)! Thanks!
