I picked up an ex-display Bic Bilbao at a good price off Ebay, and have taken it out a couple of times so far. It's fun for playing around off the beach, which is what I got it for, but it's certainly not an expedition kayak.
It is great for just loafing around it, without feeling that you need to be dashing around all the time. It feels quite strange being able to go in very shallow water, and in close to breakwaters without worrying about bashing a prop!
Looks like I've got a deal sorted on a Malibu Two and a Kea so the whole family can play.
