Shaving, Wet shave vs electric

Having spent a while chatting to the manager at Trumpers I bought a cut throat that takes disposable blades. The traditonal ones will need sharpening occasionally and it's not cheap. Whereas the ones that take disposable blades are cheaper and you save on the faffing using a strop etc.

You can get lessons on how to shave at trumpers and a few other establishments. The alternative is to practice on a balloon, cover it in foam and shave it clean. When you can do that you should be ok to do it to yourself. I did not bother with either and lacerated myself a few times at the beginning.

Cut throat is the closest shave and has the advantage of being able to remove a full beard with no trouble.

So how much do one of those cost, and how much to replace the blades? I have wanted to stop using machs for ages now.
