I found a website for them:
http://bellfiresusa.com/
No info on pricing but they have a list of dealers and distributors.
I have emailed them with questions but to no avail.
5000 sounds cheap, I was quoted 8000 dollars up in the Catskills of NY.
For that much I could just tear down what's there and build a new one from scratch.
Hey, I know, I'll go get trained to do the installations, then I'll install them for everyone for a mere 3000. sounds like a lucrative business.....
