i took an old shower unit and made it my powder booth, works well, easy to clean. id say start with at least a dual or adjustable voltage gun from caswell or eastwood you will outgrow the HF gun in short order. i built an oven extension so my std kitchen oven will fit a swingarm. i learned all the tricks off powder365.com forum, and there is a guy on there selling a used adj caswell gun for $50 which is a great price. its not hard to do but is time consuming and to do it right you need a fair amount of supplies and equipment.
