A close shave, wet or dry. (Shaving)

[rustic]

Re:- Facial hair (Just thought I would make it clear).
I have always wet shaved, but at Christmas my wife bought me a low cost rechargeable 3 headed rotary shaver, (Less than £10) to see how I get on.
It saves time and will be handy on the boat etc.

Now I am thinking of upgrading to a better quality rechargeable unit, I have looked at Philishave / braun, rotary heads, but how good are the horizontal foil type?

After my shave it feels like I have 8 hours of growth as it doesn't get as close as a wet shave.

I have seen battery versions that take 2-3 AA batteries, and mains rechargeable types, but will they go say for 2 weeks without charging.
We do get occasional shore power, and we have a mains inverter, but I don't want to run the inverter 8 hours just to charge the shaver.
Do any of you use lotions or potions, before or after ?
Any advice greatly appreciated.

I don't want to be spending £80 either.
How long do the foils last, and how much are a replacement set ?

Best regards, Rustic
