I have a Handler 135 at home and have had it for several years, lots of projects welded with it. Many arc on hours without any hitches. Many #'s of FCAW wire have been run through that little machine. It has it's limitations, duty cycle, just plan to work within those limitations. Long continuous stringers at high output will make the little machine kick out and it won't weld until the thermal switch cools off. Keep these things in mind and it does all that it is advertised to do. If you need more machine, buy one, if not, this one will do fine.

PS, Mine came with regulator and hoses, but I never have had a bottle hooked up, so I can't comment on it's GMAW qualities.
