I got my v2500 from eTronics.com for a lot less too. I just couldn't pass up the savings. I got it with shipping and a 5 year MAC warrantee for over $150 less than what Tweeter was willing to sell it to me before Tax.
also, what made me get it online was the sales guy at Tweeter who acted like I was an idiot for even thinking about buying it from an unauthorized dealer. It wasn't like I went in there and had him help me for hours and then ended up going with an online dealer. I basically did all my own research and went in there and told him what the deal was. I would have paid $100 more to get it from a authorized dealer but the sales guy was an asshole and he lost a sale. All he had to do was give it to me for under $850 out the door and I would have got it at Tweeter.
Instead, I got it off eTronics for under $750 w/ MAC warrantee and shipping.
I take care of my stuff and use the receiver maybe 3 times a week to watch movies, so I am not too worried about it breaking. If so I lose it for a week or so and have to mail it somewhere to get fixed. It was a gamble I was willing to take.
I think someone else on this site got the v2500 from eTronics and had a lot of problems with thme and thier shipping.
