I have a Daiwa TD100 loads of space, super comfortable very strong. but heavy. Got mine from fosters of birmingham, think I paid 195. Same dimensions as tournament box so interchangeable with Boss modulator system.
Thanks for the comments guys. Had a look at the Stillwater TS5 pro seat box for 170 in this weeks Angling news and i was thinking of getting this one as i could save on postage by picking it up from Glasgow angling centre.
