Best deal for ceiling hung gas heater?

Hi,

This appears to be the simplest and best approach for heat. I've got a propane source (buried tank). Looking around, I like the Reznor UDAS but it's around $1200 or so. The neat thing is that the combustion is sealed. I never like the idea of open flame in a garage. The other one that looks really popular is the Modine Hot Dawg. The good thing about this is that it's about half the initial cost of the Reznor. Does anyone know if the combustion is sealed in this one? Any other comments or suggestions are welcome!

Thanks,
Tom

Menards has the Modine copy for $400 right now in 45k BTU FWIW.

Mr. heater from northerern tool ftw. If you want a sealed combustion you're probably gonna be in that 1200 range. Do you do a lot of painting in there where you'd have tons of fumes???

Got my Mr. Heater from Northern for $349
