You can use GEM blades in it but you have to remove the spine and then enlarge the holes on the side with a punch. Perhaps Clint @clint64 could fill in some of the details.
I have found a thread over on theshavenook that details the process: http://shavenook.com/showthread.php?tid=40618
Other than the GEM hybrid option, no. But the best price I have ever found is from Gifts & Care. I checked this morning and shipped to Oregon, 100 Feather FHS-10 blades is 63,54€... That converts to about $75 today. I think when I bought 100 for my Genesis V1 about 2 years ago the exchange rate was a little better, but it doesn't vary much. Sent from my LG-H918 using Tapatalk
