Urgent need for info, on Simms waders

[Leaky33]

Have only a few days to make a decision between Simms G3 Guide stocking foot for $429 or Simms Headwaters stocking foot Chest waders for $249 or Simms Rivershed II stocking foot for 199.99 was $299 (Sale goes off in a few days). I don't give a dang about the Rivershed being convertible to waist-high. What I want is durability w/o leaks for as long as possible for the price.
Any help would be appreciated. [:/]
