I wish you luck on your building permit.
Ours took two and a half years and $30k before a shovel could even hit the ground. Building is a snap compared to getting permission from a government bureaucracy. You simply put the pieces together.
In my totally subjective lay opinion, I believe you made the best choice between the two. I came close to getting a Qfire Discovery 1 because I really liked the aesthetics... until I saw an exploded parts diagram...
way to many fussy moving parts, and one too many "automatic" features. A search for Qfire Discovery reviews yielded only crickets... bad omen.
In contrast, BK enjoys a cult following... good omen.
