I also purchased Phase II, maybe 8 or 10 years ago, and paid not much over $125 for a WEDGE type, with four or five holders. ?I'd strongly recommend WEDGE over Piston, as the grip is more secure. ?I haven't shopped in quite a few years so can't comment on the current pricing. ?I have purchased a few off-brand holders since, and they work fine.
