I electric shave and always have done bar one or two times when my shaver has been broken etc. I started off with a very basic boots rechargable, it might have only been single foil, I can't remember. I then moved up to a nicer Braun which was better but about 3 years ago I bought my first Philishave cool skin. You can use it wet or dry and it moisturises whilst shaving. It's fantastic...
I don't manual shave due to the hassle, sometimes I shave in the shower (wet obviously) or just use the shaver with the moisuriser dry.
Most likely, your current shaver is worn, most modern electric shavers shouldn't have any issues with all but the coarsest of hair. However, expect to pay £80+ for something worthwhile. Ebay actually has some fantastic deals for some reason on shavers (obviously I am talking brand new etc.!) knocking often up to 50% off RRP.
BTW: Last time my cool skin stopped working (well, the shaver socket I was using but didn't realise!) I went back to my first boots rechargable for a day or two and it didn't have a chance, it also left my skin sore. However, everybody is different.
