I've seen some from glowshift, where it has a needle for boost, and then a LCD display for Pyro, the price they're asking at the wrecker is similar to new though, I'd pass on that one in particular.
It probably would have been a nice buy, but you probably don't have a lot of extra cash laying around right now anyway.
I have this exact unit. Really like it.Hypermax - Catalog

Looks the same, except with a Hypermax logo on it.
