I use them regularly
Have always had really good results. They take a bit longer than some of the more well known MO houses because they are more of a middleman to the QBP catalogue. However, they often have prices that cannot be topped (Ouzo Pro for $258.) However, longer is a relative term - typically taking a week instead of a couple of days. I even had a return once on a defective part and they replaced quickly and efficiently. No complaints, they're in my "best mailorder" folder in Favorites along with Excel and CC.
