You'd better look for brand new SL1200G if you want something better than nearly all old Technics models. SL1200G or cheaper SL1200GR are much better than everything you have mentioned.
The blast from the past: SP-10 mkII or if you want something cheaper looks for SP-20. I've had both, here you can find my ex SP-10mkII in Obsidian Plinth and my ex SP-20 in a custom teak wood plinth.
Personally i wouldn't buy SL-1600, SL1650 and SL-1700
The cheapest is SL1210 mkII ($300-500) can be upgraded step by step, here is mine with Isonoe Feet, SAEC SS-300 mat, Grace F9E cartridge, KAB Fluid Damper, Zu Audio Mission Phono cable, Cardas Tonearm wire. I wouldn't change the arm because this is not my main system and not my main turntable. But the upgrade i've done wasn't expensive and improved the sound a lot.
