I don't think it matters what brand you buy or how much you spend....there are only 2 types of waders IMO: waders that leak....and waders that will eventually leak....that UV repair glue is a great product...keeps you going streamside, only takes a few mins to fix a pinhole
I am currently using wright & mcgill....moderately priced, came to about 250, bit cheaper maybe, and the built in back belt is amazing....the stocking foot is excessively generously cut....which makes my boots too small now...but other than that solid waders....extra layering on the knees and a good fit all over.....
got mine at Steve's in Lambeth
