Best streamer, don't want Roon, don't want a screen, A DAC is OK but not necessary

No love here for Lumin? I started with a D2 with S booster and stopped my search for a streamer/dac. I love the software and isn’t glitchy. I’ll end up with a T3 when I decide to upgrade. In all fairness I didn’t try a bunch and was coming from a pi4 so keep that in mind. Good luck with the search. 

In your price range an Antipodes CX used takes some beating.

+1 Wiim Pro Plus, used $160, with ifi ipower 2 / X or 5V/2A LPS. Don’t recommend 5V/1A.  If you don't wish to spend the extra, make sure to use old, low ripple noise Apple 10VA recharger. 

I really love the SOtM SMS200 Ultra Neo.  Super simple and sounds great.

Get a Raspberry Pi, a DAC with a TOS output and install Volumio.
