I've just purchase a Sony HDR-SR1 at Best Buy today. I'm seeing a few kits for the sony HD camcorders. Accessory Kit (http://www.digitalinnovationsny.com/Items/sonyhdrsr1withultkit?)

I was wondering if it is worth it. If anyone purchased these kits can you please give me your thoughts on it please. I really need a carrying case, tripod and extra battery. Are the lens and filters a must have? Is the battery any good and how long does it last really? I'd really appreciate any help. Thanks!!!
