HAHA, just finish a small project of JX707. Though this is much easier than my PhD's modal logic project, still drive me in tired.

Here I will show off my wonderful walkmans, and some of them were sold...

left->right: PX30, PL50, PX50, PX1000

They all look great but that PX50

I guess you think PX30 is not that good. PX50 looks OK.
