I've been taking "artistic" (non-snapshot) photographs for a little over 7 years, and it's developed into a rather serious hobby. I've used various point and shoot cameras until now (a 35mm Minolta Freedom and Canon A-540--frequently in "manual" mode). I think it's more than time to scrape together the funds for a DSLR and have settled on a Rebel XSi with kit (EF-S 18- 55mm f/3.5-5.6 IS) lens. I'm a college student, so cost is a HUGE concern for me. For this reason, I'm considering buying the XSi body and lens, together or seperately, on eBay. My gut tells me to stay away from used equipment and stick with Amazon, but my wallet tells me to go for it. Can anyone with experience buying used equipment in general and doing so via eBay specifically offer any advice on the matter? My boyfriend has bought tons of expensive music equipment from eBay sellers and never encountered any complications. Can I exect similar luck in the XSi market? I don't plan on making my purchase until Christmas, but even by then I don't expect any XSis will have been around long enough to experience much wear and tear. Any thoughts?
