I need a texture pack!

I am so sick of default! :| I want something of higher resolution, but not so high that it will cause major lag, 128x128 maximum. Modern & simple is my style. I thought of making my own, so that would be an option for me, but I'd need a little help. Any ideas? Anyone? Note: I'm on a Mac, so I kind of have to use MCpatcher, unless there is another program to use/way to to it.

I'm sure somebody has an idea here!

 

Thanks guys
