It has straight knives. It’s a great insert system but knives are more dear than the more common Tersa knives.

It’s a helluva machine. Welded underwater to prevent distortion. Knapp made stuff so good it drove them out of business. You don’t need a 16” jointer for most work. Your equipment is fine. You’ll love the mortiser but most guys today want a domino so that makes it a wash for a lot of work if you figure on using a domino anyway, minus the $1000+ price of the domino . If they take an offer of $200 or whatever you could sell the gear you have at near enough to that the machine will feel like a screaming deal.

I fear the circumstances of the company being defunct and the 3 phase power will inhibit my resale value but it can’t be by too much. Guys pay $7000 for a comparable Minimax model with no qualms.

Mine has an extension table too. The feed runs on a variable speed drive with a separate motor. The machine is built like a tank out of 5mm steel but if the internals break I’m out of luck. I hope they built it to last.

I use a 10hp rotary phase converter. It wasn’t too pricey to build with a motor I found locally on ebay. 3 phase motors don’t keep much value on the secondhand market. The converter box and wiring were about $350 I think. You’ll probably need a 100 amp panel in your shop. You can get passive phase converters (I forget the terms) pretty cheap and they reduce power by 1/3rd. 4hp would still be adequate imo.
