Thinking about getting a welder

Ok gents, expert opinion needed here.
Thinking about purchasing a welder.. Ive used MIG welder's before and got fairly good with them. I need a welder to do projects and stuff... and for working on the car with.
Ive looked at a few on C/L but Im kind of at a loss of exactly what I need for the jobs I will be doing (Axle tube welding- IE shorteneing axle tubes, light body repair etc)
Would a 110 Miller or equivalent work, or do I need a 240V mig with a gas hookup? Would I be better off getting a Stick welder? Ive never used stick welders but Im pretty good at picking up things and learning.
How much should I pay for a decent welder?
I know these have probably been answered, but I didn't find much in the search function on here. please chime in guys, my garage back home needs some new tools... Already shopping for air compressors too lol
