I used Kreg. But, after two seasons and in some instances one season, I am seeing warping/separation. I really think it has to do with using crappy wood from big box stores though. I would assume better stock would be better. I have gone primarily to ordering finger jointed (classic) supers. By the time I buy the wood and add up time putting them together, ordering them is not much more in $$. Especially using Manlake with shipping free at $100 and over. Other big names in supplies will charge in the range of $60-70 for shipping!!!!! That eats into the equation.
