And it's still a joke. Spend $200 less and get and Osmose[1] and have a keyboard that you can actually use, a better synth engine, and something that is actually used for music production. They even off free shipping. Portability is overrated when your keyboard tech is stuck in the early 90's, without velocity sensitivity let alone aftertouch and MPE.
The original OP-1 was $600 less than that when I got it for noodling around with music during my commute to work. So yes, if you choose to ignore some criteria, there's plenty of options.
And it costs what, $600-800 more than the original OP-1?
The "field" reboot is such a sad joke. All that fans had been asking for, quite literally for decades, was for Teenage Engineering to fix the supply chain for OP-1 and produce them in-volume. Instead they upped the price and made it even more rare.
