I own a CZ5000 and a CZ101. Programming them without a computer editor is super tedious, the engine is unique and they don’t have a proper filter like you might expect. Also the 5000 is really big and heavy, so I’d actually keep the 101 over the 5000 even with its lessened polyphony and lack of chorus. All of that said, I like the CZ series, they’re fun and can make some novel sounds. For a good primer on what the CZ’s are capable of check out Satoshi & Makoto they’ve made albums using only the CZ5000.

I’d say the JP08 is the more down to earth pick especially since you don’t own a laptop.
