HI-8 repair help

[Michael Ron]

One of the guys I work with has four Sony EV-S3000 Hi-8 record/playback 
machines that won't thread tape or eject. Granted, they're old but he's 
kept them around because a lot of his tape is still archived that way. 
Anyway, Sony says they no longer "support" the machines and even if 
they did they don't have the parts. Any of you know of a reputable 
repair facility that might be able to "support" a repair like this?
Thanks in advance.
