4 frame observation colony

I am searching for two observation colonies each 4 frames tall. If anyone has one, or knows where to find one, please let me know.

Four medium frames, or four deep frames?

I have a four medium frame (also fits three deep frames) Observation Hive that I built chilling in my shed that I'm not using. I'd be happy to sell it, if you are interested.

I would also be interested in building you a four frame deep observation hive, if you would prefer that. I could use a side project that doesn't suck cash, lol.

Shipping on either is probably what's going to hurt though, just so you know.
