I own more than a few 22WMR rifles, both bolt and lever action and love them regardless of ammunition availability.
Bought bolt actions for both of my sons as their first 'very own' firearms on their 10th birthdays, Marlin 25 for the oldest and Savage 93 for the youngest.
That Savage with the accu-trigger is a tack driver compared to the Marlin with any ammo.
FrankenMauser is right about the new ammo available too, wowza!
My Winchester 255 and Savage/Anschutz 141M absolutely
love that stuff!
All be it just my opinion, but the 22WMR is a stretch for coyotes though I have used it successfully on them, I wouldn't consider smaller still.
I've never had any inclination to purchase one of the 17s, though if the Savage had that trigger it may sway my decision in your situation.
Personally I would probably keep the Marlin and purchase the Savage outright as suggested, but I'm gluttonous regarding firearms.
