Dave, if you are really serious about buying a good TIG welder, go to your local welding supply and check out Miller's Syncrowave series welders. They are smoothe and reliable but not cheap. One thing to remember is heliarcing aluminum requires considerable amperage, so don't buy too small of a machine. I would be leary of buying an off-brand welder. Stick with Miller, Lincoln, Hobart or any well known brand name. I have seen some pretty good prices on the web, but you will need to decide on exactly what you want. However there is something to be said about purchasing locally from folks you can get service, info, and advice from. Hope this helps.
