Be VERY VERY wary of prices that are too cheap. You don't have to spend long over on usenet or any of the e-commerce ranking sites to discover that there's a lot of shifty dealers out there. I've heard too many horror stories about people buying DV from some New York clearing house that waits 9 weeks to ship the product (but takes payment immediately), only to find out that they won't take any returns, and Sony won't honor the warranty.
I paid about $100 more to get mine from a respectable online dealer, but it was worth the peace of mind.
For what it's worth, my own shifty-dealer story had to do with some HP 970cxi's that I bought. After getting burned once, you'll never go back. I recommend that you not learn the lesson the hard way with a $1700 purchase.
To get to cheap sites, do one of two things: 1) Go to
www.bealecorner.com. It's one of the best DV sites around, and a TRV900 shrine. It has links to all kinds of vendors. 2) Go to any shopper--cnet, pricewatch, whatever--and look up known DV equipment: TRV900, GL1, whatever you like. You'll get a list of dozens of DV retailers, and that can start you on your journey. Sherlock II does a decent job of finding good sites, too.
I hope this helps.
