WTB: Thermometer / Hygrometers

After searching my local Wal-Mart, Home Depot, gardening store, and Target, I can't find any of the Acu-Rite combinations thermometers / hygrometers that everyone is using. Well, I take that back. I've found the stand-up combinations, but not the ones with probes.

This is all I'm looking for: Acu-Rite digital thermometer / hygrometer with probe. I'm looking for 3 or 4 of them. If anybody has extras, or knows where I can get them, please let me know. I've tried the stores listed above. Thanks :-)

Still no luck at the local stores. I'm still using the stand-up type. Anybody have an extra probed one they'd be willing to sell, or know where I can find them on-line?
