I have a Line 6 UX1 amp modeling audio interface that has died. I looked at POD replacements and they are in the $500 range. I do not need anything fancy as I am just using this as an amp modeler and not for live performances.
The UX1 is my audio interface for Power Tracks 2017.

Suggestions appreciated!

For something you can gig with as well as serve as an audio interface check out the Fender Mustang I. Version 2. $120 new, about half that used.

You could also look into software amp modeling. They used to sound pretty bad, but the technology has come a long way over the last couple of years.

I'm using the Scuffham Amps S-Gear amp simulator here, Guitar Rig from Native Instruments is also quite good. Both have fully functional demos, so nothing to lose by trying them out.

You would need an interface too if you don't already have one, for just guitar the Scarlett Solo would do the job, $100 or so.
