For years I used an old heavy duty heat gun like those sold in Lowe's and Home Depot. I inherited my first one (an ancient one that saw tons of use) from my then hubby who was an electrician. When the motor finally gave out a couple years ago, I considered getting a craft model but instead went with the Wagner HT1000. It has two settings: 750w/1000w.

Good news:
On the low setting, it gets twice as hot as the 300 watt craft models without twice the blow. (Yay!) It melts embossing powder quickly. It can be used to dry ink and paint quickly. I've read that it can also be used to strip paint, roast coffee beans and bend PVC pipe.
Bad news:
It gets twice as hot as the 300 watt craft models. If not careful, you can easily scorch your paper. (The trick is to keep it moving and not hold it too close to the paper.) The metal tip gets very hot (ouch!) and it does not have a resting wire so you have to be careful where you set it while it cools.
