Yamaha has an X stand I recommend to all my customers wanting the most stable and solid stand. It's called the YKA7000. It has oversized 3" rubber feet and an offset X brace design for complete stability and comfort when sitting at the keyboard. There are telescoping arms which adjust in and out with adjustable grips at the front and back which hold the keyboard securely inplace without fear of slipping. There is a spring action hand lever to quickly and easily set up the stand to one of 6 possitions. The list price of this stand is $99.00 with selling price being much lower. This stand originally was designed to work well with the P80 piano because it would close up narrow enough for this narrow digital piano, but it also works great for all the PSR keyboards and Tyros as well.
