Back in my touring days, I had a Yamaha CP-70 and a Prophet 5. Those two went all over the pacific northwest, Canada and Hawaii. That was about $8k in 1985 dollars, not counting the playback gear. Now for my local gigs, I use a Nord Stag 3 and Wave 2, about $7k in 2020 dollars, but much much lighter! I would never think of using less quality (or less expensive, if you will) keyboards for gigging, I always want to have the best sounding and most reliable boards.
