Don't know about them, I bought the 19 piece set from Amazon for $96.95 (as pictured)...Proto Screwdriver Set #J9600C
The Proto J9600DC and J9600DCP (same set includes Proto Bottle opener) are available for less than $ 70.00 at a lot of places (Amazon, ToolUp, ToolDiscounter, etc)
Personally, I like getting 10 or 11 MORE really good screwdrivers for less than three dollars a piece!!!
Buy the set from Amazon...however, Epstein's sells an 18 piece set (minus the gigantic slothead/prybar) for $65.00...that is probably the mostest for the leastest!!! Epstein's has more on closeout (click where it says more Proto)...they have a seven piece set for $ 27.50!!!!!!
Here's the link to the screwdriver set at Epstein's---

Hope this helps---The Proto Professional Classic Yellow Handles are about as good as it gets!!!
