Also depends on the duty cycle he needs 
no point needing to weld up half a chassis and having to let the welder cool every 5 mins or less
150A welder is probably a 100% at 60A and 150A at 40%

0.8 is the standard wire on those welders, I started out with one and duty was a bit of a pain sometimes

Philip had one, if the wire feed didn't pack up, the duty cycle hit you and you had to wait for it to cool down.
The Oerlikon, runs all day and never misses a beat or the wire feed give any problems.

Only thing is I don't want to be paying out for a three phase install on top of the welder

Why would you need three phase unless you plan on running something massive like a 600A welder.......I can run 250A on single phase easily
Actually with that being said Murex and Oxford both used to make single phase 400A welders which you can still buy from Oxford but Murex stopped a few years back IIRC
I was outbid on the Murex

Stick welding is harder to master, and very easy to blow holes - while I can use a stick welder on thin steel, the mig is much easier and cleaner.
Mig is much easier to learn, BUT:-
Get a full size gas bottle - the tiny ones are too small.
Don't get the smallest welder - I have two. A 250 amp one that is brill, and a smaller 150 amp " small professional" one. Don't ask me what make, I can't remember, I've had them for 15 plus years!
You do get what you pay for - and a small professional one will knock spots off a cheapo machine mart one anyday.
Get one that takes big reels of wire.
And practice loads, with different thicknesses of steel till you have it right.
While professionals might be able to just get stuck in, I don't weld so often, so I always do a trial piece, to make sure that the kit is working properly, I have the right amps and I've got my eye in.
Practice loads, starting on thick mild steel offcuts and then progress to thinner steel.
Have fun.

Ours is single phase, albeit it does need a 32A supply.
We've got 100A/phase 3-phase at home....
