I didn't choose my heat gun, the boss just bought it. It is a porter cable he likely bought it from lowes or home depot. It has two variable speeds and a wide adjustable heat range. I have used it for over two years day in and day out with no hiccups. It also is made so it can stand up on its back which comes in handy for myself. It is not grounded though. One more thing i see a lot of heat guns fail by the variable rheostat on for the temp, i just leave mine on full heat and don't touch it, so far so good.
