I have the large set made by Bojo tools. Bought them a year or two ago around this time of year direct from the mfr at a large discount. They were worth it.
They make a number of different strengths of tools, so you'll want to look at that so you don't get ones too hard or too soft. Not much of a warranty on them, and I'm sure you know they will probably get damaged in normal use.
Snap on has a few sets, don't know if they warranty theirs...they sure look a lot like the Bojo tools, only in black with a SO logo on them.
