I've been using a MACH 3 for years.  I have an old Norelco that I use on rare occasions.  The price of refills for the MACH3 is getting rather high and sometimes I use it too long before I change blades.  Did that recently and took off more than beard.  Took couple of weeks to heal and still not quite there.Sam's has a Philips Norelco 6500 Wet & Dry Electric Shaver for $99 vs 20 MACH refills for $38.48. 

Thoughts?
