There are two pages of these on ebay. There's a brand called Mafac and a brand called Skyway. How much is the right amount to spend?

Neither . . .
"MAFACs appeal to the collector set. If you don't have a 30-yr old bike with MAFAC brakes, they're of no interest.
I'm not familiar with Skyway.
Strongly recommend Koolstop, especially the ""salmon"" colored ones. Failing that, replace like with like.

Concur with Peter.
Go here: http://sheldonbrown.com/harris/brakeshoes.html
Find the ones that match your current brake shoes. Call and order. Tell them Christian from the Bob list sent you. They'll have no idea what you're talking about.
I prefer the KoolStop Continental, if you can stomach the less-than-Dura-Ace styling.

Kool Stop Continental
"""I prefer the KoolStop Continental, if you can stomach the less-than-Dura-Ace styling.""
I agree. Best brake pads out there, and dirt cheap. I get them from Sheldon Brown/Harris Cyclery as well.

But...
The Continentals are a great deal at $6/pr, but the Dura/Campi's have two advantages:
1) The ball-and-socket hardware allows for easy, even and precise toe-in. (something that seems especially necessary with salmon pads to prevent howling).
2) The D/C's are longer, so there's more pad surface area to grab the rim, which has gotta help.
At $50 a bikesworth, the D/C's ain't cheep, but once they're on, all you'll ever have to replace are pad inserts, and those aren't much ($8/pr).

Coefficient of Friction
"""1) The ball-and-socket hardware allows for easy, even and precise toe-in. (something that seems especially necessary with salmon pads to prevent howling).""
Perhaps. I've got Continentals on two bikes; no squealing. When I installed Continentals on my wife's bike (new rim/new pads) they did squeal, but lightly sanding and cleaning the rim and pads totally eliminated the problem.
""2) The D/C's are longer, so there's more pad surface area to grab the rim, which has gotta help.""
Friction force is dependent on the ""normal"" force (perpendicular to the surface), and the coefficient of friction between the surfaces, not surface area.

KoolStop brake pads
Put salmon-colored pads on the front, black pads (harder material than salmon-colored) on the rear and voila! differential braking for 20 bucks, a fraction of what it would cost to get the same effect from Campagnolo Record ($270 !!!).
