Perks, can we have too many?

[Gudiomen]

Basic, Martial Arts, Power-Ups 2, Magical Styles, Psionic Powers... we have so many Perks it's starting to make me feel dizzy. What's worse, they're spread over several books.

Can we have too many? Are perks the GURPS version of prestige classes (something obscure and munchkiny that everyone wants)?

My players haven't sprung a bunch on me yet, actually they're simple players with clean characters, I'm the one who's likely to spring this on my GM. I'm not doing it a lot and already I'm getting the "are you sure you're not trying to pull one on me?" look.

This isn't criticism per se, if anything a variety of choices to pick from reduce the number of perks players try to invent outright. It's just something that's been nagging me and I wondered what the comunity thought...
