I will tell you my first and so far only mixed fuel torch is a Cricket.

(Well, other than the welders torch I started out with.)



But your post makes me concerned more about your ventilation.

Hot head or mixed fuel you really need to make sure you are not breathing torch burning gases.
They do real damage to human bodies and can build up over time.
Add to the torch fumes the kinds of materials used to give glass its colors that turn into gas as the glass melts and you can harm your health in ways that can not be fixed.

We have lots of detailed discussions about ventilation in the safety threads as well as pictures in some of the studio threads to help you set up good, safe air flow practices.
