Martin - I have mine 20 years. It has needed repairs twice. Our dept has
a machinist/repair guy who is fully trained in replacing the
compressors, etc. He does about one every two weeks since there are so
many in our dept. we simply have a couple of spares that we lend whoever
needs one while the repair guy gets it back up and running. The system
works great. I would recommend looking for someone on your campus to fix
your current one. It is less expensive in the long run.  Tom

Dear List--

This is off-topic but our -80 freezer (a Revco) died and we need to 
replace it.  This one lasted 11 years; I have no idea of whether that's 
good, bad or normal longevity for that brand.  --Does anyone have any 
recommendations for ultracold freezers?  Cost, lifetime/reliability and 
usability are all considerations.  I'd prefer upright to chest but a 
small chest freezer could be an option, too.

We don't need anything huge--10-15 cu ft (about 285-430 liters) should 
be fine--but it'll need to be something available in the US.

Thanks for the help!

Martin Wessendorf
