I understand Meade doesn't have the customer service level of Lunt, but the situation is not THAT bad.
Here's a link a thread from late last year. Meade accepted the PST for repair (I would like to know how long it took though):
There's little reason not to update older scopes. The way Meade/Coronado updated the design means that older scopes can be easily retrofitted with the current productions parts.
The issue is that Meade is now in bankruptcy and may have been sold. So who knows if they will repair this PST or how long it will take. https://www.cloudyni.../#entry11078112
