Does anyone know where I can find a font like this?

Cheers.

Why not just get that one?

Because I am starting up a business with very little working capital. I don't see the point in wasting $15, as little as that may be, on a font when I can get something very similar for nothing.

Well, you could try going through some free font sites and you'll probably come across something similar.

www.kottke.org has silkscreen, which may suit your needs :)

Yeah, I have Silkscreen. I was looking for something like that with entirely straight sides if y'know what I mean.
