I own a 13 inch Makita saw.
I like the size, but the Makita saws that are sold in the UK are far better and I believe would be popular among North American Timber Framers.
Specifically the 5103R which cuts a 4x4 and the 5143R which cuts over 5 inches.
I would much rather see those offered here rather than the lesser quality 10 inch and 16 inch saws they offer now.
The 16 inch is a good saw, but the baseplate leaves much to be desired.
