That's a good point about ali, I was wondering why this one stated welds steel and copper. Thanks for highlighting that.
How about this machine and supplier http://www.ebay.co.uk/itm/AC-DC-TIG-...EAAOSwDk5Tz618 anybody got any experience of this seller ?

Tig is nice but only if you want to weld materials that have heat considerations like Stainless, Ti, Ali etc or thin materials. Also To weld Ali and other exotics requires much more expensive gases like Pure Argon or Argon & helium mix etc so unless you have need for cosmetic welds and thin heat sensitive materials then for the run of mill steels then much quicker and cheaper with MIG.
Then you have the learning curve which is much higher than MIG or MMA esp when you talking Ali etc. You'll use much more consumables with TIG when learning because just the slightest touch down of the tip means stopping and redressing the tungston otherwise your always going to struggle.
Also Don't buy a Cheap Tig if you plan on welding Ali or more exotic material or thin material and cosmetic welds etc because you need the flexabilty of the settings and they are often limited.
For 5mm steel I'd go MMA for the cheapest option or Big Mig with decent duty cycle.

Well now it looks like I can't afford anything for a while. I had to buy a new office printer after the old colour laser 'refused to cooperate'. I shall be taking it for an extended holiday at the recycling centre !
I have a reasonable Mig machine, so I can live with that, but Tig would have been a nice toy. I have learned a lot about Tig in the past couple of days though.

What a bummer! If you do decide to get one in the future I can recommend R-Tech. I went down the same route as you by the looks of it and ended up spending slightly more on an R-Tech unit. The service and returns was the main thing that swayed me, didn't fancy sending a faulty machine back to china! Its been faultless for 5 years now. I also got mine as an ex display unit which brought the price close to £300.
Regarding the gas, I used Forest Gas in Lydney for pure argon if you're around that neck of the woods. I also use BOC argoshield for MIG on the volkszone offer, not sure if they are currently offering it but it was cheap at about £50/year rental and £25 fill.
