We can't afford one at the moment - the doc actually prescribed her an inhaler, but without medical insurance, it costs over $50. Right now is a very tight financial time for us, I have posted about it in my first thread I created about an inverter here, I will not repeat that as it got ugly quick.
I already have some drier exhaust hose, and I am going to rig up a 120mm fan or a small blower to the thing for when I need to solder - I just have to find a way to exhaust it outside effectively without causing a huge temperature drop in our room (dorm room like living, bedroom for now, next month or soon very likely a studio apartment).
