I bought the kit on sale and also joined the buyer's cllub. Very easy to use. I joined the powder coat forum after about a week and asked a few questions about problems I was having. Got straight forward answers and never looked back.
I've had excellent results. Any shortcomings are due to my limitations and not the equipment.
Plan to start building a larger oven next week.
Buyer's club also saves money on powder and shipping. Already got my money's worth in shipping alone.
