I've done a fair amount a research myself on Mini DV. If are looking for a high end DV camcorder, I would not go with the GS series. Its a very good camera for its price range, but I would still drop it in the consumer camera box. Now, it depends what you're shooting, how serious you are and all that. It might be perfect for your purposes. At the top of the camera pyramid you have the XL series by canon. Then, still up way high in the sky you have the AG-DVX100a by panasonic. Then there's the VX-2100 by sony and the PD-170. All of these are great cameras-if 1. you're serious. 2. you will be shooting a lot (These are not cheap!).
Then below these high end cameras you still have some really good ones. Theres the GL series by canon, the AG-DVC15, 30, and 60 by panasonic, GY-DV300U by JVC (I would stay away from it), and PDX10 by sony. These are your prosumer cameras.
Then, a step below these you start getting near the bottom of the food chain of good mini DV camcorders with the AG-DVC7, and the GS series.
Make sure you do your research before you buy, and above all TEST THE CAMERA! I would recommend renting it if you can. It all depends are what kind of shooting you're going to be doing. Good luck.
