PM'd you but i'll post anyway.

I have the 450w VX and it's a great budget PSU. build quality is pretty good (not as nice as the HX but good enough) it's whisper quiet and will handle pretty much any single graphics card without a problem.

I've never had a coolermaster PSU, doesn't sit right with me to be honest but i'm sure it would be fine.

At £40 the VX would be a no brainer for me.
