Wanted to buy Sun Nuclear 1027

I am looking to purchase one (possibly 2) Sun Nuclear 1027 Continuous Radon Monitors. Let me know what you have.

I have a 1028 i purchased a couple years ago and took my classes but found it easier to let someone else do the test, so I only used it once in my own basement to check it out.
I know it will need to be re calibrated ( I guess) so if interested make an offer. just sitting there
you can e-mail me at grega@ohiothermal.com

If you guys have something to sell, please pm me. Thanks.
