...My criticism: $4000 is still a lot of moolah - unless you are in the top 10% of wage earners! So I will just make do with my vintage 1200 (maybe get a new mat!).
The SL1200 debuted in 1968 for about $350. Adjusted for inflation, that's about $2534 in today's money. Given the improvements in features, build quality, and performance, $4K for the new version isn't so out of line, and the price of the SL1200 GR is spot-on, adjusted for inflation.
