I have a 30x50x10 stick built garage with 3 garage doors, 2 walk doors and 4 windows. I installed a MrCool 36k DIY heat pump system and could not be happier. Cool in the summer and warm in the winter and the cost is very low.

You should definitely triangulate the ends to insure against rolling. Difficult to weld on now, but you could...
I used a Spyder hole saw with carbide teeth to bore through brick and sheathing for a 4" bathroom vent pipe. The Lowe's stores near me carry them. Cost me $50 bucks for the saw and arbor. I priced renting a core drill and bit at $150. I then used the same hole saw to bore through roofing...
All of your comments are subjective, speculative and highly opinionated. The question is "will the funds help out people in need" and the answer is most certainly "yes".
Who gives a rats a$$ if SBD gets some recognition?
Some people find the bad in anything..................
I got several quotes from local companies in my area. I wanted someone close by to call when I had warranty or service issues.
