Not sure if it's to late to help but I bought an MTA 181 from MIG, TIG, Arc and it's a great piece of kit which will go as low as 20amps for thin stuff and up to 185amps for the heavy stuff
They build these in house to the same spec as the Portamig 181 and it's an excellent quality finish with great components (sadly way too much better than my skills at the moment but I'm getting there!)

I initially used CO2 pub gas but switched to Argoshield Light from BoC as they are still doing a special no rental deal for "Y" size bottles (bigger than I was expecting at around 40KG but excellent fill pressure) through Vzi at £61.31
Good luck with the search and hope this is of some use
I considered the MTA, but in the end plumped for the portamig 215, it goes to an even lower minimum, to 15amps, comes with a quality 2 stage regulator, and I was able to specify a 4m torch for the same price, I chose the 215 not because I need more power, but the increased duty cycle and apparently it has a better quality gas solenoid, meaning that its worth the £50 extra, mostly it will be used on bodywork, where the 12 power settings and low amperage are essential.
