So, as everyone else is voting for the DD 3x3, I'll throw a bit more info into the mix.
My current preferred tarp for lowland use is a British Army Basha in DPM camo. It costs 20-30 quid, has plenty of space, and of course in most of Britain you won't see it when setup.
I also have used a German flecktarn poncho as a tarp, it's very light weight, but only covers 2m x 1m. But that is plenty if used with a bivvi bag to keep your head dry.
If you don't want to go the camo route, alpkit make various sizes of tarp, their 3.5 is about the same size as the army basha, but it is green and has a few more loops to allow you more variety in pitching.
If you want to go very light weight, then the RAB Siltarp 1 (available from many places, including Backpacking light. It's more expensive than all the others, but it's also a lot lighter.
These give you a small cross section of some of the tarps that are available. Ultimately each has their uses, and which is right for you will only be arrived at by trial and error. You pays your money, you makes your choice.
Happy Camping
