i have ordered lots of parts from mac's over the years. Figuring shipping and handling, the true lowest cost to my door has usually been mac's. I have been happy with the quality, they are always good about telling you when a part is quality or not. If i make the decision to buy quality, or less so, thats my decision and i live with it. I have ordered from most of the parts houses and have no problem with any of them. We in the model a hobby should be happy for the plethora of parts options we have available. Mac's catalogs are a wealth of info, no matter where you place your order. I have no interest in getting into an argument with anyone about anything, just posting my perspective as this piling on mac's gets a little old. They definitely have their place among the model a parts houses.
