Don't know St Martin but Yorktown is a poorly constructed cabinet line with nice finishes. That's why Toll Brothers builders use them. If you are selling a house it's not a bad selection, but if you want your kitchen to last it's not a good pick. There are many well made cabinet lines around these price points, some would be: Kraftmaid, Woodmode Brookhaven, Bishop, and Decora. Consumer reports and JD power are terrible sources for cabinet reviews by the way. If you want a well constructed cabinet that will last a lifetime:

1) It needs to be framed and not frameless construction.
2) It needs to be all Plywood and no particle board with 3/4" shelves and at least 1/2" sides.
3) It needs to have solid wood dovetail full extension blumotion drawers.
4) No Thermafoil
5) I prefer a solid wood hanging rail like the lines listed above but a 1/2" slotted back panel is OK
6)I beam construction is best or solid wood corner blocks are OK.
7) There are many well made even less expensive cabinet lines, some even from china, that meet these requirements. Some have finishes that aren't quite as nice but the cabinets are well constructed.
