About a year ago I backed a Kickstarter project for a wetsuit dryer. It finally arrived and I have used it a few times.
It's basically an enormous coat hanger with air vents, a fan, and an electric heating element. There's all sorts of technical data and tips on the web site.

So far, it's pretty good. I can dry a 6mm suit from totally dripping wet to completely dry in two hours (one hour inside, one hour outside). I washed the suit in a tub of fresh water, let it drip for 15 minutes (to reduce the weight of water), then put it on the dryer and turned it on. The hanger grips the shoulders fairly well so there's little risk of damaging the suit, provided you let it drip a bit first.
If I let the suit drip dry overnight I can turn on the dryer in the morning and the inside will be completely dry in about 30 minutes. The ends of the legs might be a bit damp.
At this time of year in Melbourne a wetsuit can hang outside or in the garage for a week and still not be dry. I can use heating ducts at home to dry wetsuits but that can be a nuisance. During road trips it as always difficult drying a suit overnight in a caravan park cabin. With the wetsuit dryer I can quickly dry a wetsuit whenever, and wherever I need to.
