1. Here's a Hickok meter for $99. It is not for 600A but maybe someone knows if it would do. Electrically I think it might be either fine as it is or with some adjustments , physically dunno.

And here's a 600 using the same size(and likely the same) head.

2. A 600A is a fine instruments, bought mine close yo $400 and it's case is not that good looking. I still think it is worth every penny. If you can have a known good head for $200(negotiable?) it still might be worth it.
