Bay thermostat replacement

Has anyone replaced the  "White-Rodgers™ 2B61 Line Voltage Outdoor Mechanical Thermostat" in the wet bay with something else? If so could you forward the make etc along with pictures.
Apparently they do not make the original anymore for my 98 U320 with the thermostat "bulb"

Ok ..so maybe I will phrase the question abit.
 Does ANYONE have a spare basement thermostat they would kindly relocate to myself at a reasonable cost?

That the thermostat has been discontinued a while back but I was able to find a new old stock on eBay for about $40.

Peter, that thermostat is an on/off switch based on the temp of the air it is in.  So any A/C thermostat of that type will work.

Yes as discussed similar thermostats will work although I would like to keep the convenience of the bulb end so I can position the sensor anywhere
I think I found one
Would this work?

I am not sure as I read it is open and close on rise. I think you would need open with close when temperature goes down. I could be wrong, but that is how it looks to me.

Dayton/Grainger thermostat in reply #4; first picture says spst (single pole single throw) and second picture says spdt (single pole double throw).  I believe if spdt, it can be wired as either open on rise or close on rise.

I bet you are correct about the spdt.

SO not being an electrical guy, is the spst (single pole single throw) correct or is the spdt (single pole double throw) correct.?
They make both models and I want ot ensure I purchase the correct one.

I would go with the spdt and also note that it says "switch action open/close on temperature rise" which is what you want.
