I recently bought a power adapter for my tablet, Gateway CX200. I bought this 90W adapter with power output of 19V ~ 4.74A not from Gateway, but from HP . Its lead is not a perfect match to the tablet but it fits good enough. I have been using this from last week and it works fine. So if you want to save roughly 35-40 bucks then purchase HP adapter from eBay, instead of a Gateway one.
