Freeze dryers are usually prohibitively expensive, so that’s a deal.
However, I think the failure point is in the vacuum seals. Do some research before you buy, though at $20, you’re not out much.
I have a job interview next week, and bidding on the dryer ends the week after. I think if I get that job, I’ll buy the dryer as a celebration :)
(When most girls say “shopping spree”, they mean clothes and jewelry and designer shoes. I go ga-ga over lab equipment. I’m such a geek!)
