Im a miller fan even though my big machine is a lincoln..lol If you want a machine that can do anything than a multiprocess machine is what you are looking for, but they are very expensive.. You cant go wrong with a mig welder for a fun easy way to learn, and you can get a big enough one that will keep you happy.. Heres a mig Ive been looking at.. Millermatic 212 MIG Welder Auto-Set with Spoolmate 200 951177 .. I really like cyberweld for their prices are very good and Ive had very good luck with them ordering and customer service... If you havnt already got to millers web site and check out their machines.. And the welding web forum has alot of info on it..

Thanks
