I want to buy a two-person inflatable kayak and was keen on the
Sevylor Colorado or Stearns Back Country which are about the same
price, but I've just found a Sea-Doo IK at Costco which is much
cheaper and includes paddles. It's not mentioned anywhere on the
Costco web site and I know no-one who has one. The IK will be used in
sheltered bays and shorelines, canals and local lakes - no rivers or
white water. Can anyone advise on the best option please?

This could be a troll, for instance by Costco marketing shills,
but in case not, here are two web pages Kooky45 should read:
