Does anybody have any experience on the regency products ? Either burning ,selling, servicing ? I'm looking at a new fp90b it appears to be very similar as far as firebox etc.. As the newer ex90 can you give me an idea on what a new Excalibur 90 sells for. And also any info or experiences with the fp 90 b. I can't seem to find any reviews on either unit and have been searching pretty hard. Any info is very much appreciated thank you.
