Most anything can be bought on eBay cheaper than other retailers. I buy there often, but one must be very cautious as to quality. If it says Made in the USA it's probably good quality. If not, it may be questionable. Sometimes it's a crapshoot.

I agree with James's suggestion. He should probably be thought of as a national treasure.
I do have one caveat, not all screw slots have parallel sides some are tapered. I've seen this on more than one high end German gun. I have a theory on how this was done but I'm not for sure so I'll keep my thoughts to my self. My point is don't assume anything. I've modified a few old wood handled Grace screwdrivers just for that purpose. BTW, I love wood handles they just feel better than plastic.
One other passing thought on screw slots, CJO and I were perusing the fine shotguns at the Southern a few years back and he said "look at this!" a Rizzini R1 (I think) had the narrowest screw slots I've ever seen. I have no idea how they assembled the gun tightened and timed the screws!

Doug,
The slots that are tapered are filed rather than sawed. My German gunsmith friend, Walter Grass, usually sawed the slots, but every once in a while he would file one. Now I wish I had asked him why. At the time, I thought it was for those small wood screws that wind up much thinner on one side than the other( in trigger guards, etc). I may have been wrong.

I have cut screw slots using a clockmaker's file, which I bought from Brownell's some 25 years ago. It cuts parallel slots though, not tapered, but narrow. I guess I could make it cut a tapered slot, if I had any need for such, which I don't. That is one unique little file. It will bend in a gentle curve if needed.
I see they do not sell them anymore. I'd better guard mine carefully.

Stan,
A favorite file is like a member of the family.

The kind words about me are appreciated.
There are still screw slotting files available as I have seen them on line. I bought some at Friedrich Dick's in Deizisau, Germany many years ago. Grobet still makes them.
That said, the finer they are, the easier they break. They must be used in a holder. They are also expensive. However, if you want a tapered slot, nothing else will do.
It is best to anneal the head before you start or you will ruin the file. Start the slot with a with a fine jeweler's saw, or a hack saw blade with the kerf ground off, then finish up with the clockmaker's file.
The idea of a tapered slot is similar to a taper shank drill. The possibility of a tight fit is easier than parallel sides.
