Has anyone ever used a toy repair service? I've found a few vintage toy restoration businesses that accept out of state clients where you mail your items for repair and they send them back to you.

I collect vintage Japanese toys and have been successful in cleaning up battery compartments and restoring toys to like-new, working condition. But I now have two inoperable toys (one from 1984 and one from 2006) that I can't get working due to the extend of the battery leakage. I'm considering using one of these repair shops but was wondering if anyone else has used services like this.

I bought both of these toys for $30, purely for collection purposes, but they go for ~$500 in working condition, which rarely pop up for sale anyway.

Picrel is one of the pieces I'd love to bring back to life.
