Hello, Must say much thanks to GW and the rest of you crew for the years of research I have been able to study over the past two months. I will have an mk3 assembled very soon with most bells and whistles, just need to find a recovery pump and don't quite want to settle for appion or equivalent. There are several options online I have been looking at and quite a few large HVAC stores in my area I am just not sure how to approach the situation in a price vs quality situation. I have no personal experience, only recent studies and would appreciate any offerings. I am an engineer at heart and am so motivated to pursue high quality BHO. Safety > quality > quanitity Any tips please share!
