I've had an ES-8243K for several years. It does a nice job on my dome and can be used wet or dry. I normally use it with Lectric Shave but I make sure to clean the blades carefully afterward.
One thing about electrics in here, there are three schools of thought in SBGs. Group One is the guys who stand by their blades over all else. There is no shave like a blade shave. Group Two is the electric crowd. No matter what they are going to shave with an electric. There is no room in their shaving kit for a blade.
Group Three is where I land. I mostly shave with a blade but I fill in with my Panny. To be sure the blade gives me a closer shave than my electric, no doubt. But I find that if I did a blade shave in the morning and I need a touch-up later on that day my Panny does a more than acceptable job. My dome shines after going over it with the electric just like it does after a blade shave but there is a minor velcro feel to it but it is not noticeable to anyone but me.
I've had a few electrics over the years and in my opinion the Pannys are the best of the herd. I don't think you'll regret your choice.
