Seeking repair recommendation for HP 67

[Marcel Samek]

My HP-67 has two problems.

1) One of the digits (7th from the left) is completely dead on the display. Calculations work as expected so it appears to be a display issue.

2) The card reader needs to be refurbished. It runs, but not well enough to actually read a card.

I am trying to decide whether it is worth getting this unit fixed.

I am looking for recommendations for a repair service with a good reputation so that I can get a quote. I have googled around, but it would be great to get some personal recommendations from this forum.

Thanks.
