Submersible Water Bath Heater in the USA?

I’d like to do my own E6 processing but for various reasons I can’t get a constant a constant 114F out of the tap. I’d like to find a submersible water heater that I can use in the water bath. Submersible fish tank heaters will hold +- 1F but only go up to about 93F. Nova Darkroom makes these:

and

But I can’t find a USA version and even if I did an international order voltages are different in the US. I bet there must be something outthere I can use to keep my waterbath at 114 or so.

Any Ideas?

Thanks

OOPS Answered my own question 114 is the mixing temp NOT the developing temp. 85 Degrees is a lot more doable

I use this aquarium heater to pretty good effect. I was able to get a decent deal on it when it came up on Ebay.

Before I bought Jobo, I used a cat litter pan with 2 100 watt aquarium heaters. I locked one full on, and used the other to adjust the temp. it worked well.
