Thanks for the replies everyone. Very helpful.

I will not be going for that razor, after all. Absolutely happy to spend a lot more on that, but do not want to spend too much in case I ruin any of the equipment.

AxelH - The gel I use is a King of Shaves gel. Seeing as I can tell you this, the razor I use is a Gillette Fusion. What are training wheels, and will this razor have them? Also, what would be the advantage of using a double edged safety razor over this? Can you recommend any? I have heard that a German company called Merkur do a pretty decent one.

Thanks again for all of the advice.
