I want to scratch my itch for a 10mm and looking at the Delta Elite. I have heard that the "newer" ones are better. Hoping those that have them, new, or old, will chime in and let me know what you like about them, and what you don't like. Haven't heard many bad things about them. How do the new 2019 models stack up against models from a few years back, and against the original models. Any model year that stands out? Thanks in advance.
