I previously had Deuter but now use Pacific Outdoor Equipment panniers. I like the POE panniers a lot and did not like the Deuter's all that much. The POE panniers attachment system isn't quite as nice as Ortleibs, but it is very good and works perfectly well. Not quite as quick to attach and detach. The POE panniers are big. I have the small panniers, which are universal (front or rear) panniers that are as big or bigger than regular Ortleibs and rear specific panniers that to me are huge, and they aren't even the largest ones POE made. The panniers I have are from their expedition line and can be seen here. They are very waterproof, quite durable, and I would recommend them. The POE's offer plenty of room and an internal compression strap to help hold the load towards the bike and keep it from shifting. More than enough room in them for any tour I can conceive. I will say that the reason I went with them is that I got them for a great price since POE has been bought by Hyalite.
