I think they are all made by the same group of chinese prisoners/organ donors.
Many folks use Taylors.
Many box stores carry them.
$15-$16 should buy most any of them.
Often you can get three for less than $30 from Amazon and free shipping.
I give them, as gifts, to relatives,friends,etc that I might have to cook for.
Most of them interchange, amongst different units.
Of the many I've seen ,over the years,the cable is the least likely to fail.
Taylor web site replaces the probes for less than $5?
Hopes this helps a little.
