Some more (some) at Soopah's request:

7.
8.
9.

8 and 9 are great

nunber 9 is also another i think is good

I like number 9 very much; I'm assuming the "O" resembles the on/off logo?

I think it would look good to have the "O" as an on/off logo, it just needs tweaking to get looking right.

i vote we use 9 til the competition comes in. its gonna take some beating.

Cheers, But I don't think it would be fair personally, and I expect its far from a fore gone conclusion, as I know we have some good photoshoppers here. I think nexus is going to come up with some really good ones, judging by the small amount of graphic design work of his I have seen!

And anyway what's wrong with the current one, don't go upsetting knighty

my very very basic attempt I'll put abit more effort into one after the missus has stopped moaning for me to tidy the house,

You do not need to do that though 72dpi logos can be made fine without all that messing around. Vector things, text though should not come out pixelated at all, actually wondering how that has happened there?
