I've had a XP-80 for about 10 years, but operating it is becoming a major pain in the ass, since most buttons have stopped worked or require excessive force to work (actually some don't work anymore).
I was thinking about getting some quality push buttons and taking all that crap out (I don't mind losing the red leds), and solder them to the pcb.
Would you recomend me any online store or switch model before I start searching?
Thanks
