To go with the 'worst' thread, let's have your opinions on the best for the money.
I'll kick off with Exped dry bags.
Usually just forgotten about after you buy them, but you look at them every time you get your kit out, usually not noticing them.
Value for money and very well made in my book. I've got most of the sizes except the really large one (had to have a Karrimor SF dry bag to go with my Sabre SF, 'coz I'm worth it.)
