Aristokraft is one brand of Shrock Cabinets.Shrock is presently owned by Masterbrand and is 20 miles from my home and I have several friends who have worked there for years.They build several different grades.
You can view their website at www.masterbrand .com

sorry but i am pretty sure aristokraft and schrock are not the same. they are both master brand but so are kraftmaid, dynasty, etc so that has nothing to do with the cabinet.
schrock is diamond/thomasville/kemper.
aristokraft has another brand name also but i can't recall it. i just replaced builder grade aristokraft with medallion silverline and was ocd on researching cab companies. lots were just out of my budget.
my very basic oakland held up for 15 years but were not looking pretty. look at the aristokraft website to get the specs on the particular cabinet you are being quoted.
this is a very good site to research cabinet brands. opinions will vary widely depending on who you talk to but cabinets that should be close in price to the aristokraft are some kraftmaid, medallion silverline, some kemper/diamond/schrock and quite a few more that i can not think of.
look for a thread on here comparing painted shaker cab prices done by a KD
