We used Semihandmade in our library - the base cabs are Ikea kitchen cabs ( pretty solid, the kitchen cabs ) and these guys did all the doors.
I cut down the depth of the Ikea kitchen cabs at the local TechShop, and cut tons of holes for cable routing. Found a shop in LA which specialized in large grommets and all was fine.
That worked out so well ( and was under the $300/ft quotes we were getting for maple) that we hacked up another Ikea / Semihandmade for a hallway cabinet / workbench.
Working with this crew was a total pleasure.
