Hi, I'm looking for a Pop'n Controller 2 (ポップンコントローラ2) for Pop'n Music on PS1/PS2, like this one:

Please note this is the later second model with round buttons (The original model has flatter buttons and usually transparent casing, with old Konami logo).
In good working order, I don't mind the colour or box.
