@audphile1 I've been looking at Sutherland's phono stages as well and have similar thoughts about the TZ models. I'm not sure I'd want to limit my cartridge choices due to the TZ design. A 20/20 or something similar would probably be the option I'd go for.
Back to the OP's question, I haven't heard any of the Graham Slee phono stages yet, but they seem to get a lot of love. Another alternative might be a used Parasound JC Jr. or JC3+.
