I find with the Busy Bee stuff you really need to be selective and expect to rework quit a bit of what you might purchase there, I've learned to remove everything that's possible from a package while I'm at the store and inspect it thoroughly, of course with some items this is impossible, I purchased a mill about 12 years ago for some heaver work that my hobby size mill could not handle, I considered the price verses what use I would get from it and just accepted the fact that I would need to strip it down and inspect/rework what ever was necessary, and the lack of quality control did not disappoint, I had to do every bit as much or more work than I had expected to, but I did know what I was getting into and it was what I could afford.
I've found the staff here at the store in Dartmouth Nova Scotia very good to deal with, the problems I've had is the times I've needed to deal with the people at the head office, I might have just been unlucky but the couple of time I've contacted them the people I've dealt with just don't seem to care whether there customers are happy/satisfied or not.
I purchased what was advertised as a super precision milling vise once, it rocked .025 from corner to corner and each side had a .015 dip in it....? I fully intended on re-machining it because I wasn't about to make a $60 trip to exchange a $100 vise, I called them just so I could express my dissatisfaction with the product, I honestly thought that they would be interested/concerned, but I was absolutely wrong, the guy I spoke to said no problem it will flatten out when I tighten It down, I asked if he seriously considered this to be an acceptable solution, he asked me what I had expected, I said I expected some level of accuracy seeing as it's advertised and sold as a "Super Precision Milling Vise" I was told some people are just to fussy an can never be kept happy....?
