I honestly think theres no point using an electric from how much hair you have, and how often your going to use it :P
I would recommend a manual Gillette, just get a standard mid-range one. Cheap = bad blade, hurts like hell if you cut and will cut more often. Expensive = waste of money for how much your going to use it for.
Hope it helps
(Also get some sensitive after shave balm, since you're new to shaving, your skin will feel a bit funny and the shock of starting shaving could irritate your skin, only use a small amount after shaving to leave your skin fresh and rash free! )
