Heres my classic 500 write-up. http://www.hearth.com/talk/threads/brand-new-bosca-500-classic-up-and-running.91938/ I really like my stove. Paid $1000 out the door for the stove. All the motors, limit switches and augers are generic pellet stove industry standard stuff. Ignitors are less than $20 through grainger of the like. I have read on this forum tha the board is identical to a St Croix Prescott board as well.
