I have the 10' pelican sit-in kayak from Costco for the last 4 years (with the discount was around $250cdn comes with paddle and roof mount foam system for vehicle and spray skirt), mounted a rod holder on it and it has served well.... the only complaint I have is I wish I had a sit ON (instead of a sit IN) and a 12' instead of a 10' (a little more sturdy, but nearly double the price); fishing wise I find it a tad tough to reach around with the sit IN (also, me belly could use a workout so as not to get in the way as much LOL).
If it's a kayak you're after, Costco has the 10' pelican (don't look online, those prices are way higher than what they sell in the store) - they go on for $75 off every year. If you go to the States, there's some good deals.... Home Depot if you can believe it has some really good prices

http://www.walmart.com/search/?query=kayak HOLY WOW - just looked it up, HUGE SALE ON NOW! For the price, I was looking at Sun Dolphin Fishing Kayaks (sit on)... They're on for $278 US (for the 10' - $121 off!!!) - comes set up for fishing!!!
http://www.walmart.com/ip/Sun-Dolphin-Journey-10-Sit-On-Fishing-Kayak-with-Paddle/32333500 If price is the big issue, the non-fishing, sit IN is on for $188 US. Just add a rod holder... all come with paddles.
This goes against the buy local theme we all prefer, but I don't know of anywhere you can even come close to prices like those around here (or anywhere in Canada). Sun Dolphin is made in the USA, so I don't think there would be duty on them, even if they did ask about it - I often have come across with that value (2 of us in the car usually) without being asked to pay any duties anyway.
