I have read good things about the LBT as well as the cabin tree, both run about $100.00, I own the Saeco its more expensive and I don’t know its worth the extra money, I have had it for years and it works good for me.
I don’t know how old you are, I know a lot of guy’s say the cheap Lee tester works ok, they do say it’s hard to read. If your eyes are getting old, I would not waste my money on the Lee.
