I understand just wanting a new table, and the VPI is a really good choice. It's a known quantity, with factory support. You might also consider the newer Technics DD offerings. I'm using a 40+ year old Technics myself.
If it were me with $2K to spend, however, I'd probably buy a Sutherland phono-pre, new or used, and spend the rest on a better cartridge. The TT is just there to turn the record at a stable speed, and support the tonearm. And they ALL do that, tho some better than others. The cartridge and phono-pre have WAAAAY more influence on the sound than the TT itself does.
If you just want a new deck, go for it! It will probably make your Nagaoka sound better. But a better cart on the deck you have now will likely be a bigger difference. In my opinion.
