You can throw a lot of money at all this but my best-bang-for-the-buck + fewest hassles after the sale + does its job better than most:
MW: Genius Panasonic is a MUST! - not built in! - on its own power circuit
REF: We did very well in 2013 with on-sale Samsung-RG257 although not all reviews are 5-star like mine
DW: Kitchen-Aid's interior setup & cleaning superior to all, so long as No Food Grinder (a bad idea that is now past, I think); indeed Bosch will last like a tank & Consumer Reports' fav but ... been there done that German engineering w/o good American designing
Range: 1980 still going strong, some knobs no longer say "hot"/etc. Jenn-Air downdraft electric w/glass top panels plug&play that can be exchanged
TComp: Kitchen-Aid has always ruled here
Ice: Scotsman has been the icon always
Layout: most will keep the coffee bar, Ref. & MW flanking the chef's work area to keep those frequent invaders from being underfoot
Most common equipment in our designs:
Cookie shts/MW-sh/OV/Dwrs tall cab
Range/oven (no pot filler); upper class hood/light/vent-to-outside
Ref - recessed into wall 7" or flanking cabinets get deeper by 6" for B.I. look and superior cab storage
SS large sink w/Disposer & R.O. water system (also runs to Ref)
DW (x2 is rare)
TDwr w/outlet for future TComp
W.I. Pantry w/appliances counter (lots of outlets)
Island w/16-18"d Knee Space & tough material kick back for those on stools; pendant lighting in vogue now
Bar - coffee, colas, beer, cocktails w/deep drawers for 1/2gals
Of course we all love Wolf, SubZero, et al. and of course if on sale, then .....
