Cart sites rarely update their reseller list after it gets populated.
If you're looking for fast shipping to the US, modchipcentral.com ships out of canada so you can have it in two days.
If you're looking for cheap, lightake.com is a new shop people here have been recommending and I have yet to hear anything bad about, it ships out of china so it won't be nearly as fast to get to you depending on the shipping service you choose.
