MIG welders - which one to get?

I wanna buy a MIG welder in the near future and I don't know what to get. What does everyone else use if you have one? I don't know whether to get a cheapy ebay one or spend the dollars and get something decent.
So far I'm leaning towards spending around $800-$1200 on a decent one. The Cigweld Transmig 200 seems like a good bit of gear and is around $1150 but I may be able to get away with the Transmig 165 which is around $900. There are a few other brands around which make similar spec welders (WIA, BOC, UNIMIG, Lincoln etc) however I can't seem to find any prices on the net and I don't have the time at the moment to actually get down to the shops to check them out. Is there any other models I should be looking at in that price range?
Most of the stuff I'll be welding will be thin metal mainly automotive stuff, things like aluminium cooler pipes, fabricating steel brackets etc etc.
