Thanks for that...sounds a little like the "mattress store" business model where the same mattress is sold under a different name in different places, maybe with a few changes.
By either model number, this is a fun one. The dance/EDM sounds and styles are pretty interesting. Lots of ethnic sounds and styles, too. Keys feel better than any $120 keyboard has a right to, although I do notice the keybed has a little flex to it. Speakers are good but the amp runs out of steam pretty fast if you have to turn your headphones up too high. I'm pleased that it works well as a MIDI controller too, although it may put my smaller Korg MicroKey out of business! I'm actually considering seeing if the numbers work for trading up to a CT-S300 for the pitch bend and touch sensitivity
