For smokes, I just augment my HVAC system with a portable A/C unit in the room where my humidor and cooler are.
The cost is negligible as there is only about 4 to 10 degrees differance from the Whole House system.
A/C units have been much more reliable tha vinotemps, in my personal experience.
For wine, I honestly think I would go with a compressor over a Thermoelectric.
Not knowing a true expert's take (say somebody like Josh or David) as it relates to what wine itself might prefer.
I just know that a compressor fridge is one of engineering's more perfect designs. They last forever.
I read an article years ago where the Engineer/Author stated that a fridge compressor can easily last 30 years, with many lasting 50 plus. They basically very rarely break.
He went on to say that you can go to a junkyard, and most of the refrigerators there will have been thrown away
for everything but a failed compressor. Door seal, color not liked, redecorating, finish damage, etc.
