I recommended one of these to another forum member and he ended up buying it and i have heard since from him that he is pleased with it.

I had one briefly but it got badly damaged in a flood. Before that though, i was impressed with the performance for the money.
Its not the best machine out there obviously but it is easy to use and works very well.
Might be worth considering?
as stonemonkey said above, it's well worth getting the adaptor to run the hobbyweld or adams gas cylinders if you plan to do a lot of welding as the small bottles run out in no time!
