This is a great bench. Holmenkol. You see a lot being used. Not super portable. They weigh a ton. But they are rock solid. Adapt to uneven flooring. Adapt to any ski length. Racks for skis and brushes.
I've worked on a lot of other portable benches. Beast, Swix, etc. IME, no comparison.
This is Artech's ad. They are pricey. We have three. Total cost for all three combined was a fraction of the current price here for one. If I were in the market, I would still buy this one. We have owned ours for 15+ years. They last.

Way to expensive and too short to boot!
