Superb. Absolutely superb.
I've had a 50 gal tank with built-in refridgeration unit down in my basement for a couple years now that was used to hold collected coldwater marine organisms for a lab: slate bottom, double-paned glass, etc. It can drop the temp down to around 43*F. I've been wanting to revamp it and get it up and running, and this thread has reinspired me!
Steve, I think I can get you in touch with a few divers/coldwater hobbyists in the Seattle area that should be able to locate you some strawberry anemonies if you can make the trip up to get them. I'll drop you a PM with some more info.
And again, great work!
