HELP, Pls - re Automatic Turntables, Vintage/New

Am new to Audiogon but most impressed with the expertise reflected in these posts... Hope you can help me. I'm looking to replace a vintage Denon DP-52F turntable (fully automatic), owned by my 90-year old father.

My dad is an avid audiophile who has traded well over the past 50+ yrs... System includes Audio Research receiver (no model # on face but its '80s-era combination tube & transistor unit), McIntosh MC2505 Power Amp & a McIntosh 2100 amp, McIntosh MR-67 FM tuner (tubes), 2 original Altec-Lansing VOTT speakers (A7s), and 2 Tannoy speakers, one being the classic GRF Corner Horn.

Turntable has been the weakest link... In part because, as he's aged, hands have become unsteady; he needs an automatic table to position the arm for him.

Would be MOST grateful for suggestions on possible replacements for his DP-52F Denon. Have thought to look for other vintage/automatic Denons, but parts availability seems to range from spotty to nil. Have also considered Technics, such as SL-1300MK2/1600MK2... But apparently they have common problem with cueing & auto-lift(costly fix).

Any thoughts on other makes/models to look for -- vintage or new -- would be appreciated. We have a modest budget (up to perhaps $600, give or take)... But dearly hope to find something that will sound as good as that old Denon.

Many thanks!!!
