So here goes... First this does not contradict my other posts about.... wait for it... Busy Bee tools. They put a piston type AXA post on sale from time to time for about 268 with 5 holders. I own one, and it has served me well.
My experience has been good from ACCUSIZE.
That being said, if I did it again, I'd go with a wedge AXA from Shars, and buy a few of the AXA-XL toolholders from them; the XL holders accommodate a wider range of tools than the standard AXA (which I use as well). I currently have 9 toolholders, and am about to buy 5 more. Even with the shipping and duty, you'd save about $80 when buying a post and 6 holders (pretty much the minimum you'd use)
