Seb, I'd endorse the advice about looking for something secondhand if you're on a budget. It might be worth looking at something like this:

or cheaper but poss more of a risk:

These mig units are no longer produced but have a good reputation and were built by Cebora so you'll also find them listed as a Cebora Pocket Mig 130 or Turbo 130 (the Turbo bit just means it has a cooling fan) as well as Snap-on. SIP 130 machines are also readily available but ( from experience) I'd avoid them - there's plenty of comment on this forum about the smaller SIP machines and you can probably do better for the money. The smaller Clarke welders 135 and 150 are also worth looking out for but ask on this forum for direct experience of these.
As for gas it's worth doing a bit of research looking for BOC Argoshield Light as a basis. Adams gas, amongst others do rent free cylinders and will likely have an agent near you. A cheaper alternative to start with might be to look out for a local pub gas supplier - they sometimes also do welding gas but possibly limited just to plain CO2.
Finally if you have any steel stockists near you it's worth asking if they have any of the edge banding that protects the sides of the steel sheets that get delivered to them. This is often thrown away but is ideal for bodywork repairs and you might get it free if you ask nicely.
Good luck with the Jag project.
