The altimeter on my CC11 (MyPanel option) has failed it's first 24 month check - "very sluggish in operation and also baro subscale out of tolerance". I'm not hugely surprised as it has always misread the altitude when set to QNH.

Apparently it is an expensive unit (~$4k) intended for standby use in a turbo or jet and has been shaken to bits.

Obviously it's out of warranty and in any case seems to be unsuitable for the application or it would have lasted more than 200 hours. Any suggestions as to a sensible replacement?
