Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
I have an older GOSM that has worked real well for me. The temps don't waver and it's solidly built. They don't make the model I have anymore - it's all stainless - but I would take a good look at what GOSM has to offer.
