all sold

tells you how much i get on lately.. i just saw it but voted yes anyway even though matts already a mod. he'll do a great job just like hes done as a seller. :)

one of the guys over at PL said that hes used a high temp grill paint and exposed it to 5+W of yag and the thing didnt break a sweat.. i think for costeffectiveness i may just have to go with the paint if i can find a good one. that would probably be cheaper than having them anodized too.
