I have a regular KORG but I still enjoy playing on both foldable keyboards that I take with me on trips. The larger one has both cable and bluetooth midi. The Blackstar only has cable midi. If you don't have room for 88 keys, you probably can find 61 keys or even the smaller casino keybord.
This one has LED lights (it uses led lights to teach demo songs):

Without lights:

This one doesn't have weighted feeling and the keys are lighter and smaller:
