I've had a Snap On / Cebora 130 Turbo Mig for 15+ yrs now and it's a great little welder.
Got mine mounted on a Clarke Welding Trolly with a full size gas bottle but they can easily run on the small disposables as well.
There great for welding body work (about 1mm to 1.2mm usually) when on the lowest setting or can give a decent weld on 4mm sheet so long as you take your time and have it on the higher settings.
You can pick them up on E-bay for £120 to £170 for a good one and are generally far more reliable than the equivalent Clarke, SIP or Sealey jobs.
I've been thinking of upgrading mine and getting a bigger MIG for years but always seem forget about it as the Snap On / Cebora does pretty much everything I need it to
