I am looking to upgrade/replace my tach and trim gauge. I only have a tach right now, so matching gauges, looks wise, is not an issue.

I see Teleflex at a lot of places, and it's hard to find other brands at a reasonable price. Is that my only options? Teleflex or big money??? Thanks.

Basically, teleflex has been in the business so long no one has ever come close to giving them competition.  Your choices are the primo gauge companies or go with manufacturer gauges which are often teleflex gauges in disguise.
