Anyone still make a 1" steerer suspension fork?

You have to find old stuff , the standard has changed to 9/8",
so make, new, highly unlikely to none. .

hit the bike CoOps for 2nd hand , or stick with rigid forks.

The Marzocchi MX Pro was available with 1" steering but they stopped making it last year.

As with all suspension forks, cheap = junk. Good = expensive. The problem is worse on 1" forks because now there is no mid-range left, only the very cheap and the very expensive. Having ridden junk suspension forks and decent ones I would rather ride an old rigid fork than a 4-6 pound pig RST fork.

Suggest you look for a new-old-stock Rock Shox fork. There should still be some floating around on ebay in the low $100 range.
