Thanks for the replies guys. (And sorry for the slow post - I originally posted near my bedtime and went to sleep shortly after.)
For SlimRider: How long of a life on aluminum can I expect? I don't need a legacy bike or anything like that - just something that is reasonably-durable and a good value. I read in a few places that aluminum bikes can be well-built and are generally less expensive than other types. Do you have any thoughts on that?
My old bike had straight bars, so I am used to that. Is there a functional difference between between drop and straight handlebars, or is it a matter of preferance?
For hybridbkrdr: Thanks for the suggestions. I'll look into them.
For quattroG: Thanks - I took a look at Google and it did show several closeout deals. I'll make a suggestion about the price at the bike shop if I decide to buy.
