I have been looking for an affordable dovetail jig and found several "Central Machine" jigs on eBay. They are sold by Harbor Freight it seems.

The problem is that it only comes with a 1/2" comb and the other two are no longer available. Does anyone have these or carry them elsewhere?!?

I think it would be worthless without the other combs, even for $35 price on Harbor Freight's web site...
