Looking for ideas - Decent cheap 26" 1 1/8" suspension fork for 1996 Trek 950 mountain bike
Honestly, it seems that you want too much of everything at the same time: cheap, good, compatible with your depreciated frame suspension fork. You might reconsider your constraints.


Compatibility comes first, otherwise there is not much sense in getting a new fork. You'll need something for 26" wheels and with a straight 1⅛" steering tube, which is not what modern forks offer. I would say the majority of aftermarket suspension forks are for 27.5" or 29" wheels and likely to have a tapered 1⅛" - 1½" steering tube.


Then you have two remaining exclusive options in the requirements space.


Cheap — find a new OEM fork for entry-level bikes. There are decent chances to find something for 26" wheels, with V-brakes and straight steering tube. But such a fork is not likely to turn out to be "good" in terms of suspension performance and longevity.
Good. Go for a hunt on vintage market or consider having a modern fork with all mandatory upgrades it brings with it. Neither option would be cheap. For example, a new MRP Loop SL for 26" and straight steering tube costs USD 800+. Add to the price the front wheel change (through axle), front bake change (disc brakes).


Yet, finding a used old fork still looks more promising, and there is always a chance to find a deal.

On the last compatibility note, the 60 mm of travel is something not commonly seen for MTB these days, even on entry level forks. There is e.g. Lauf Carbonara gravel 
fork, but it is not something you'll want; besides, it is not straight steerer neither for 26" wheels.
