I just picked up mine today from Serge at The Video Clinic in Santa Monica. My HVX was fllled with grit and sand from a helicopter shoot that I did. Serge does great work and my HVX is as new. I think if you are still under waranty (The Video Clinic is a Pany authorized service center), I think the tabs are free or a minimal charge the first time around. If you are out of warranty, I think they are about $400.00 to replace.
