I'm assuming you are talking about a shavette. Electric fires is not a thread title that gives me a clue...

A shavette is a CHEAP way of seeing if you like the workings of the straight razor shave. Yes they are more challenging to use then a "real" straight, but you still get the idea.

I would rather spend the $20 and see if I liked it before spending at least $ hundreds on a QUALITY straight, strop, etc..
