I’ve also been in that situation and considered something like a Roland Integra 7, which can be found for around $1k in good condition if one is patient and willing to buy second-hand from Japan. I already have a pretty nice Studiologic 88 key hammer controller, but using that with Ravenscroft 275 on an iPad with an interface, mixer, preamp, and the speakers in the living room (studio monitors) is still a pain to turn on and use when we want. Acoustic pianos are obviously the most immediate, but a Nord or other stage piano with powered monitors is pretty convenient too.
