Remodeling basement and purchasing a wood insert for an existing open masonry fireplace. The fireplace is quite large, so we're looking at the large inserts, so it doesn't look like a microwave. Opinions as to best options for a flush mounted, contemporary unit? Currently between Lopi, Regency, and Osburn. Any others I should be looking at? There doesn't seem to be a large amount of choices in wood inserts. Also, while I like the Lopi large insert, the quote I got (approaching $7k installed) seems nuts. Thanks!
