bszaronos,
The comments by compusolver and osborne5 are valid if you intend to do low-light work. But I didn't see anywhere in your post where you mentioned low-light or event shooting. If you will be in control of the environment where you shoot, or you're shooting in daylight, then a GL2 would be fine. For low-light work, the Sony VX-2100 has a very good reputation.
As for where to buy, the general consensus seems to be B&H (www.bhphotovideo.com). It will be more expensive than some, but is very reliable. If a place is offering a deal that's too good to be true, there's probably a catch (gray market or incomplete package). As a rule-of-thumb, if a web business also has a physical store you can go to (a "brick-and-mortar" location) it's a safer bet. If you have some time, you might wait for a manufacturers rebate to be offered. Over the past few years, I've seen several rebates offered on prosumer camcorders. A little over a year ago, I was able to get my Panasonic DVC30 (similar to the GL2) for $1550 by taking advantage of a rebate. :D
If you're buying used, you don't know what condition the record heads are in. So it's a crap shoot. On rare occaisions, you can get a bargain price on a new camcorder that was recently discontinued and is being "dumped" on eBay. There seem to be companies specializing in buying up lots of recently discontinued products, then selling them on eBay.
Just my 3 cents worth :)
