Has anyone used the timing belt kits off of Ebay?

Next up on the list of things to do to the 2003 Santa Fe I picked up is the timing belt. If I buy the parts at Napa I am looking at around 300.00 to 350 for the parts. If I get one of these kits off of ebay, it is considerably cheaper. Has anyone used these kits and how is the quality? I don't want to use junk, but Ive heard of GMB and I thought I heard good things. ANy feedback on these kits? The link to the auction is below.

Thanks
Bob
