Carbatec sells the jig for $87 now. It is a quality copy of the Dowl-It jig. There are knock offs of the knock off available for less on the usual sites but their fit and finish looks really rough in the best of cases. If you're getting the quality knock off, it is surprisingly not much cheaper than Carbatec on ebay or Aliexpress.
Edit: And of course, now that I've checked, you can get a version of the jig delivered by Amazon USA to your door, for ~$22 less than Carbatec.
