I now own a couple of CNC'd SS razors and they don't shave any better than a clean Tech but they look nicer being machined instead of stamped. When I read about $300+ razors and how much better they are than a good vintage Gillette, well...I would say don't bother with vintage Gillettes, modern razors are soooo much better. (Thereby leaving more in the wild for me to potentially find)
But seriously, and I'm just another echo in here, everyone should have a Tech. There's a reason Gillette made them for so many years. And the Slim is one of the best razors ever made.
