I agree. When you pay a professional, you're not just paying for their equipment - you're paying for their experience (such as gathering people for group shots) and creativity. Not to mention, an entry-level DSLR alone is going to be pretty bad for indoor photography. The other thing is that friends and family are going to want to enjoy the wedding, not be busy taking pictures. A pro won't have any sentimental attachments, and won't miss any shots because they're busy doing what people do at weddings. That isn't to say it can't work, but is it worth the risk? On the other hand, there are a lot of awful wedding photographers out there, so it certainly doesn't surprise to hear people say that their friend took better photos than the hired pro (in these cases though, that just isn't saying much). Anyone can put together a portfolio of a few good photos, so when you're looking to hire somebody, I would ask to see an entire wedding's worth of samples.
