Why dont you buy a plateburner on E bay? That is how I got mine and they are great for alt printing. I would love to have an Edwards HO unit, but at $1500 I can get 5 plate burners, or 1 plate burners and pt/pd supply to last me a long while.

My times are a consistent 11 min, the bulb lasts a long time and you can dodge and burn if you feel the print needs it, that is what I dont like about the Edwards units, they are self enclosed.

Good luck.
