I have the unit from TJ'so and it works really well. Great instructional videos too!
The cure racks are a MUST have! Worth every penny.
The advantage of using a fluid bed is that the powder pain't will go on much thinner ...so you don't get drips when you cure the paint in a toaster oven. Too much paint is probably the beginners biggest error.
Go get a cheap toaster oven at Walmart. .curing them makes the paint 100x tougher. Cure time info on the TJS site.
Watch their video on how to tap paint off a brush for the back of a jig (or throat)...it takes a little practice but once you get the hang of it your jigs can look A+.
