New to DAPs, trying not to break the bank

Hey y'all. Been reading a lot of the posts already here, but not quite finding what I'm after. Essentially, I'm looking for a DAP that functions more like a classic iPod than a smart phone (god knows I don't need more distractions at work). I don't need to be able to stream music. Offline playback is really what I'm after with some playlist curation features and bluetooth support ideally. The snowsky echo mini looked promising, and I especially like the idea of having actual physical buttons, but the lack of gapless playback is a turn off.

Not sure if what I'm looking for is out there/in my budget (~$150 ish is my upper limit but I do love saving money lol). Thanks :)
