Whelp, I ended up going to a few more bike shops in the area, and was told more or less the same which put my mind at ease a bit. I ended up going with the Indie 3 after test riding a few. It felt good, and damned if it isn't a sexy beast. I went to the shop like a kid in a candy store; I got my bike, a helmet, a pump, a multitool, and a bottle holder, and rode home.
Took 'er out for my first real spin today -- a brisk 4 mile jaunt up and down a local bike trail -- and I tell you what: I knew I was in for some surprises, having not been on a bike in ages. I was prepared for throbbing legs and a sore rear end, and to be fair I did get both of those things in small part. The thing I didn't expect, which took me out of the game before either of the others could, was my hands. It's time to get me some gloves, methinks.
