The Fox flatbed method feeder is a reasonably good method feeder but is quite difficult to mould your method mix around being a flat construction, i've also found when retrieving the rig that some method mix is still lodged well in the centre ribs of the feeder, wether this is a good or bad thing is still a good question. Expect to pay somewhere around £1.80 each and they are available in two sizes.
