RockShox MAG21/MAG10 but look for 1994 versions and after as they have improved response to the trail buzz over the earlier MAG forks and you may as well get the better ones.
OR RockShox JUDY in 50mm format, very hard to find but you'll probably find you'll be happy with the 60mm versions and run some slightly softer springs OR a wide range spring (like Wings Spring) and less pre load. It's what I'm currently running, the spring react well and the handling is fine for riding (unless you're into really twisty turny stuff, but I keep up fine with everyone

) Still running 130mm stem no problem.
Using less preload and less damping with the longer travel (60mm be it JUDY or MAG at 60mm) lowers the front end a touch as well as giving you a smoother setup to remove trail buzz (well by buzz I mean small bumps).
This was one of the reasons to use the 60mm travel MAGs over the 43mm one's as you could 'soften' them and still have 40mm usable travel.
At least that what I've found and
JUDY are probably easier to come by but are heavier especially if springs are fitted, but hey not really going to matter as comfort needs to come first.
Proabably a bit waffly in the typing as I'm rushing
Not saying don't look at other options but they are both common forks and I don't know much about the others
