Your original link doesn't seem to work, but here is the machine I bought from Sam's:http://www.samsclub.com/shopping/nav...=5&item=180053
I've had it for 2 years now and pop corn in it often. I use the Gold Mdeal megapop 6oz pre-packs. Great corn.
The machine is great; I have no complaints. I clean it after each use, which is kind of a pain but worth the effort, IMO. I've had no issues at all with anything mechanical on the machine and it seems really robust.
