personally i much prefer mig and get the most powerful you can afford, a euro non live torch and the ability to take larger rolls of wire (15kg) and a regulator for normal gas rather than the little hobby cylinders...
a welder will pay for itself a 100 times over if u stick with classic cars, mines built wine racks, garden planters, gates, numerous landies, so easy to deal with sheared bolts and loads of extra times it'll help
i had a sealey for years and it was a decent enough machine (180a) however look at the second hand pro makes that come up,
i was lucky enough to be outside our local secondhand shop the moment he stuck an ESAB 200a MIG out for sale, spot , stitch n weld functions, proper earth clamp, 4 metre torch so never need to move welder, and a brand new ARGOSHIELD heavy 5ft tall cylinder with regulator... new over £1800 at the time so i bit his hand off at the £100 if u pay cash :0
unbeleivable deals do occasionally come up
