check out the model year changes on the Lynch website:

any hummer (h1) you get will be noisy, but it's certainly not a bad riding truck (especially considering what it can do out of the box). As far as the year...depends what you will do with it. Do a search here as well as on the HML and you'll get a bunch of info. Flashoffroad.com is an excellent resource as well.
