Replying to Mounting Bindings

Hey guys. I just got new skis and I want to transfer my FKS120s to the new ones. I took them off my old skis already so I just have the bindings. I was wondering if I absolutely need an FKS jig to drill the skis. The bindings have spacers under them (they give me a template to drill through because I can tell which holes on the spacers the screws were in). I have never drilled skis before and was just wondering if it was actually that hard. My local shops charge $70+ to mount skis and I dont really want to pay that much if I can just do it myself. It seems easy enough I just wanted to get your opinions, thoughts, advice. Stuff like that. I would obviously get them checked out by a ski tech after I did mount them to make sure they are safe. If anyone has a video or a step by step process to explain/help me do it, I would appreciate it. +K for help!
