I built an a/b box, very simple and easy, to switch between amp and tuner. Now I want to move on to another project. I will have about £30 to spend, and I already have a soldering iron, drill etc, so don't include tools in the price.

I was thinking of building a ruby (inspired by Kerry's robot ) but I'd rather make something which will benefit by live sound. I've been looking at the orange sqeezer http://www.generalguitargadgets.com/index.php?option=content&task=view&id=47&Itemid=79 and you can get a kit for it for £30.

Any other reccommendations? Also, should I get an orange sqeezer kit or buy the parts on their own? The kit would surely make it easier, but I'm worried I'd end up paying alot more for it.
