Mellotronists

Hi,
Though I don't have a 'Tron yet (still hopeful),
I am interested to know how those of you who have Trons are able to 
preserve the tapes...........so here's an informal poll...

These machines are growing older by the day, so I wonder:

1) Do you use your mellotrons regularly?
2) If so, what measures do you take to protect your tapes from decay 
(i.e. shedding oxide, temp and humidity issues, etc.)
3) What can be done to prevent "stretching" of the tapes due to age, 
overuse, etc...?

there's probably a dozen more questions that should be asked, but 
this will do for the moment.....

I nearly bought a M400 last year on ebay...a beautiful machine, 
judging by the photos, but at $3000+ plus shipping from the east 
coast to Alaska, I was unable to justify the purchase to my wife....
I remain hopeful, however.....

Meanwhile, I'd be very interested in your responses...Thanks in 
advance!

Paul
