A few weeks ago I picked up a small heater at Lowes as a) it was on sale, b) I've got circulation problems so if I get cold when typing my fingers go numb. Amusingly it still gets a little cold in Florida occasionally, so for $11 it was worth picking up to have available if it was needed. Today the room I was going to be working in was a bit too cool for my liking - the windows had been open to dry paint, so it was a perfect time to try out the heater.
