Get a MIG, practice until you're consistantly good. You can weld your pipes just fine with the MIG. When you finish welding your pipes with the MIG, you can can use a flapper disc on your grinder to make your welds look even beter. Someday after you are completely confident with MIG welding, find you a deal on a TIG. I wouldn't suggest anyone buying a TIG for a first time welder, that's silly.
