The technics SL1200G is excellent for the price. I managed a comparison with a Rega 10, I preferred the direct drive.
I did have a very expensive Vinyl set up with a Kuzma XL dc and 4pt arm which I had to sell due to moving house. The Technics matches the Kuzma in many ways maybe not quite as expansive or powerful but more accurate tonally and that is with a lesser cartridge.
Having owned a range of phono stages (ypsilon, AR, BAT etc) I believe the phono is as important as the TT.
I have heard good things about the Dias.
Isolation of the TT is very important.
However I would not bother with vinyl if starting out now as my digital sounds so good.
