Looking for an avionics shop in NJ or eastern PA. I want to get an
IFR moving map GPS installed in my Archer. Don't have the budget for
a GNS-430 or CNX-80 so I'm thinking either a KLN-89B or the Garmin
GPS-155XL. Any other thoughts in that price range? I'm hoping to
keep the entire bill under $4k. Any experiences with Penn Avionics at
Perkiomen?

Thanks,

Ken
