I had mine redone by Dymag a few years ago and IIRC the cost was circa £160 for the pair.

As for sale / buy price, back then mags would be circa £700 - £800 (and non-mag were £450 - £600).

So depending upon quoted costs for refurb, I'd say mags that need redoing should be sub £500 maybe £350 - £400?

Not 100% sure of current prices though, but hope this helps.
