I see the facom sk stuff on ebay pretty cheap too. Those are real nice in my opinion but nothing fancy.
End of the day...they're just screwdrivers. If you spend the time to hunt them down you'll find that they're not much better (if at all) than more available drivers from other companies like wera, wiha, or the sk made sk drivers (very similar to wera; not sure if they're rebrands). Just a screwdriver, you won't get nightmares for having a different brand.
Get the part number of the screwdriver set you're interested in and enter that part number along with the brand name into Google search; that's the fastest way to find sources.
