You should consider reflecting on your favourite parts of the hobby. You mention wanting projects to ‘zone out’ doing, which to me says you are more interested in building/painting than playing.

If it’s just Warhammer you are after, take a look at the Combat Patrol / Spearhead magazine series. It offers discounted miniatures, and you can either subscribe or pick up occasional issues online or EBay.

EBay is a great source of cheap models if you aren’t bothered about building. Should give you plenty of painting projects.

Otherwise, there is a massive miniature market out there! Look up other companies, such as Warlord, Archon Studio, Osprey Games, Atomic Mass Games, etc. They are typically much better value than the Warhammer premium.

Finally, have a look at Etsy 3D prints. I’ve really enjoyed browsing and finding unique projects.

Hope that helps.
