Did you give them all a plan with exactly what you want (size of cabinets, drawers, pull outs, etc? You need to compare apples to apples and can't do that unless you give them exact specifications.

I'd get ultracraft.

I've worked with UltraCraft for years, I really like them. They are a good solid cabinet !

Get out of Kemper Echo and do standard Kemper. They are more comparable to Ultracraft. Or look at Dynasty or Medallion, which is Schuler at Lowes.

You need a list of cabinets and trim pieces that you give them. And don't let them ad anything else. That is the ONLY way to get a realistic comparison. Although they have mostly lined up in order of quality correlating with price. Except for the Siteline. Strange that it came in so high.

"Custom maker" doesn't say jack about anything real. Faux custom guys abound who order drawer boxes from one company, cabinet boxes from another, and doors from yet a third company. And then assemble it in your kitchen. And then glop house paint on them, and everything else. A true craftsman, who makes everything himself, from 3/4" Baltic birch ply with Grass hardware, and then finishes it in his clean room, with a catalyzes finish, would not likely be anywhere close to only 22K.
