+1 on that gun from Michaels w/ coupon.
Takes a while to heat up (don't they all), but it can gush glue when it's hot, is easy to control flow, and comes with 4 nozzles. Also has good thermal momentum, so it can be unplugged for a minute or two and the glue still flows. I don't trust low temp glue here in the south, but the high temp (with a dot of Gorilla glue here and there for to make it permanent) works well. YMMV on the glue, but the gun is good.
