Jeremy See is surely doing a great job as a YouTube blogger, he's nice to watch and knows his stuff.

Yamaha's marketing strategy is indeed rather cruel. I was going to mention, that Korg PA700 should be compared to PSR-SX700, not to PSR-SX900, but now I see that PSR-SX700 doesn't really have a "chord looper" function. It makes me say "what the... did you, Yamaha, take time to intentionally put away some parts of a code, just to make the difference between two models more obvious?".

But in the same time, watching the videos I heard Jeremy playing saxophone on PA700 and I'm not sure that I liked it as much as I like saxophones on Yamaha, and after all the sound of voices is more important to me than all the unique things showed about PA700.

Currently I believe that it's more useful to have a collection of various keyboards, as I see that sooner of later any keyboard may end up in a service for several weeks, so you may need a backup and even a backup for your backup, and it seems silly to have like PSR-S950, PSR-S970 and PSR-SX900 instead of products of different brands.
