For your first welder in the shop I think you made the right choice. You can easily weld steel and stainless steel, and with the right sleeve maybe even aluminum(although you might have to buy a spool gun if the wire keeps jamming up). TIG welds are, for the most part, superior in both quality and looks(if done correctly), and the TIG machine can weld any metal with the right gas. However, TIG welding can be fairly temperamental and it is much slower than MIG. Cleaning and joint fit up become much more important. Also, out of position welding is much more difficult, especially if the piece is too large or heavy to flip around. Crawling over a large piece with torch, filler rod, and pedal can be very frustrating(but amusing to watch). In the end you'll want both welders in your shop. Sometimes the speed and ease of the MIG will outweigh the better looks and quality of the TIG.
