Pads Set Yamaha

Where can i find a cheap electric drum kit?

I am looking for a preferably full size electric drum kit to practice with at home. I have a yamaha pad set which was good to start out with but now I need something bigger. I cannot get an acoustic kit as I live at home and my parents would killlll me. So, what can I do? Also, price needs to be kept kinda low as I have few funds.
Thanks.

Really the best electronic kits are the Roland ones. But those run into the $1000’s just for a simple kit.
In addition to the page I posted check on e-bay. http://search.ebay.com/search/search.dll?from=R40&_trksid=m37&satitle=electronic+drum+kits&category0=

Good luck with the kit.
My husband has an electronic kit. Comes in really handy when the kids are asleep.
