The Walsh PB bumbag is tried and tested by generations of fell runners. Mine is still going strong (although reinforced with duct tape inside since 1985.
Pete Bland Sports in Kendal is the place to get them.
However, I have since moved on to the Lowe Alpine Fjellrunner - it has a broader waist strap and the bag is a bit more capacious and fits better without bouncing. I can easily fit in waterproof top and bottoms, supply of Mars bars, mobile phone, plus the dog's flexilead and it also has a clip to hitch your keys onto.
Up and Under seem to stock them, but I've never used this store so couldn't vouch for them.
Nathan make a couple of models but I think these would be too small for your requirements.
I would suggest that as well as looking for a bag with a reasonably wide waist belt, you get one with side compression straps to minimise bounce - the more flattened, sausage shaped bags also seem better in this regard. I've always found the squarer bags (eg Camelback Flashflow) tend to give me a bit of chafing in the lower back.
