Here is the "no hole" thing from the same company. Played with one at a trade show and it was mind blowing. Super strong and 100% invisible. They get you on the consumables though. Same with the Zeta. But since each fastener can save you more $ in labor than the few bucks each fastener costs, I think they are worth it. I don't own any of their stuff yet but will at some point. They guy next to me just got the basic lamello joiner (not zeta) and it is so well made you cannot believe it. Even the wooden box it comes in is awesome. Makes Festool look like something you get from the Big Box.If there was a way to utilize that without the hole I think I would be more interested in it for me.
