Gig bag for PSR-SX720?

[Pianotone]

Hey all!  Waiting for my PSR-SX720 to arrive, now looking for gig bag options.  The Yamaha one isn't easy to find (SC-KB650); anyone have that and if so any thoughts on it?  There's a Gator one GK-61 that looks nice but it's pretty expensive, I used to have a GKB-61 but it appears too small for the 720.  There are a ton of cheap ones on Amazon, but not sure I want to go there either . . .

Any input would be much appreciated!
