Have had the Douk Audio tone arm life for 6 months now. The are about the least expensive at $87 with shipping from China. Works fine seems well built. 

I bought my first Audio-Technica Safety Raiser(AT-6006 ) in 1980, for $19.98. It worked flawlessly, for over 30 years. Then, something apparently dried out and it began lifting more abruptly. I found two NOS/NIB pieces, on eBay, and bought both. Well worth the money, even at nearly six times the original price(each). It now appears to have been re-released, by AT(the AT6006R). From the outward appearance; the Douk is a Chinese knock-off. https://www.ebay.com/itm/Douk-Audio-Automatic-Tonearm-Lifter-Arm-Lift-For-LP-Turntable-Disc-Vinyl-Re... and here’s the new one, from AT: https://www.audio-technica.com/cms/accessories/398e4995e9bfe926/index.html It seems both companies have eliminated the lock-down/lift-defeat wire, of the original(not a big loss). ie: https://www.vinylengine.com/library/audio-technica/at6006-safety-raiser.shtml  Any of the three, would have plenty of room, between the arm mount and platter of a VPI Prime table.
btw: I found placing a tiny O-ring, on the AT6006’s cylinder, to save my correct height, went a long way to simplify the adjustments. Holding it both vertically and horizontally, exactly where I wanted, while tightening the screw, was just too big a pain, in the confined space between my particular arm and platter.
