Cash back on already discounted piano. Don't know much about them but just bought one for beginner level. Keys seem to have a good mechanism based on review. There is a better discount on the s1100

For those who are interested
For anyone considering this for themselves to learn/play piano at home it's a pretty good option. The PX-770 is a pretty decent keyboard at this price with the stand and the key action will take you very far. I haven't tried the PX-S1100 but with that stand and the loose pedals it looks more suited to performance/mobile and wouldn't give the same value to a learner and the "Smart Scaled Hammer Action" isn't as good as the PX-770.
