I have a Cannon and recently had a problem with the keypad on the lock. They have excellent service and are in the process off getting it fixed with absolutely no cost to me. The issue was with a bad batch of keypads from several years ago, so I don't think you would expect to have an issue if you bought a Cannon. Mine meets all the specs that you mentioned and cost me $650 from Costco.
