Standard co2 tank + regulator vs Titan co2 generator

I happen to run across this generator! http://www.titancont...generators.aspx and I'll probably be getting a co2 timer also if this is the one I'm going for. It seems really expensive tho.. $500+ for this setup. Is it worth it or should I just manually add co2 and check it on my co2 meter?

What do you guys think of this compared to a standard co2 tank and regulator?

Depends on your room. Do you have trouble controlling heat during summer? The burner is going to add heat and adds another fire risk. I have used both and prefer to use a tank and digital ppm controller. My bottle 20# bottle lasts me over a month.
