At work we have a 160 amp Parweld (XTS163DV which is more than your budget), however I'd happily recommend one of the other models they do that is in budget.

I have put a cebora in the for sale section, good stick welder but a very basic tig!
Probably get flamed but ended up with a Hyundai 160 amp for £87.99 ! 2 year warranty not too worried about tig for that price!
