We are getting ready to purchase a stove for next season, I have had a CB 5648 for 15 years and then went back to indoor wood burner. Ready to go back outside, we are contemplating between the CB 6048 and the CR 7300MP. I am wondering if anyone could give me some insight on these units, I am hearing that the CR 7300MP is more efficient than the CB, but want it first hand from someone that has burned one of these? Any info or input would be great, thanks in advance!
