What Lightweight Tarp?

[slarge]

OK, so I have a bivvy bag, a light sleeping bag, and now need a tarp. Sort of thing I am after is about 7x5 feet, and 200g and £50 (and green or dark colour). What are peoples recommendations, (I am happy with 2nd hand if anyone has something surplus)?

Siltarp1 ticks all boxes.

Used mine a lot and still going strong.

Thanks, looks like exactly what I am after - just need payday to arrive!
