Personally, having used the VX-2100 and the GL-2, I’d say they’re both fine cameras. I don’t think either one is going to be "obsolete" soon, either.

Your budget and your desires would define which one to get, I suppose. The GL-2’s are great cameras in general, but can get grainy and lose color depth in dimly lit churches. On the flip side, with the $250 mail-in rebate going on for the GL-2, it’s about $650 cheaper per camera than the VX-2100. But you have to keep in mind that a lot of your savings will have to be spent on lighting to make up for the deficiency of the GL-2, and some couples don’t like lighting at their weddings.

The VX-2100 has less zoom range, and can be a hair more basic in some regards, but all in all, it’s a pretty slick camera. Plus, it’s good down to 1 lux, so in the least lit ceremony you’ll get good picture. Again, more expensive, but then again, you won’t need to drop a grand on a lighting setup.

If you won’t be doing a whole lot of low-light stuff, I’d say stick with the GL-2’s. I like em. I own three of them. If lighting is a concern, and you’re willing to pay a little more, the VX-2100 is for you. I’ve also got one of these, and I am very happy with it.

EDIT to add: Don’t bother with Hi-Def yet. For what you described yourself as doing, you’re not going to need it.
Hope that helped some.
