whats your budget ??
I moved ALL my stuff from the RED Craftsman (see my link below for pictures) to a CRANBERRY KLR761 (54w x 24d) - i didnt have alot of extra room after filling the main roller cabinet (klr761) so i added a side cabinet....and honestly that was enough space for me, w/ some room for growth...the opportunity presented itself, such that i could move up to the BLACK KLR 7023 (72wx29d) w/ the full stainless top.
Because of the 7023's additional wide drawer (vs one in the 761) i actually have a couple of "thin"/narrow drawers empty (for now).
the MEDIUM depth drawers are more useful, for me...and the LARGER depth drawers are the LEAST useful, to me.
It really depends on what you do & where you work - if you were in a shop for a living youd probably want or need some deeper drawers and a side locker.
im finding slightly used (12-18 month old) snap-on stuff on craigslist for 30% or LESS than retail - find it on craigslist or ebay and make 'em an offer (surely theyre willing to deal).
this isnt isolated pricing...between a friend of mine & i we have purchased 4 boxes and either flipped 'em (for profit, after using it) or kept 'em.
