I would like to get a bicycle that I can use to commute to my college campus as well as use for recreation. I have looked around on these forums and others trying to learn as much as I can but it can be a bit overwhelming with everyone's different opinions and advice. My commute would be at least 10 miles (getting to and around campus) a day and I would like to do some recreational riding on the weekends. If I am going to get a bicycle I would like it last to last at least my 4 years of college if not more. I guess my questions would be: Should I buy used (Craigslist, eBay, etc.)? or Should I buy a new bike and if so, from a LBS or from an online dealer? I'm leaning toward a road bike because after testing a few, I like the more forward leaning position rather than the more upright from MTB and hybrids. So any models that can be suggested would be appreciated. Thanks in advance, any advice will be helpful.
