Jig shoe question

Looking into jig shoes and wondering if anyone knows why the Hullachan Prestige Jig Shoes are discontinued. I have Hullachan ghillies and absolutely love them, and was looking into their jig shoes. Sadly it appears I've waited too long to buy a pair within the US. I have Rutherford Jig Shoes right now and I just honestly don't feel like they're the quality of several years ago - they feel much more 'bare bones.' Would Fays or Corrs have an equivalent to Hullachan?
