Did you make a purchase? Seyvlar do another kayak called the Riviera that looks quite good, although i'm not sure they included a keel. The intex ones are often on sale on Amazon though worth keeping an eye on HDUK.
I got out last weekend onto the River Lune which is near Lancaster. About a 30 minute drive from my house, but it was much nicer than the canal. Probably one of my favourite paddles so far. Got around 2 miles downstream and then came to a series of weirs so turns around as didn't have too much time. I hope to return and look at portaging to get around them and carrying on. Also went down a very tiny weir which was excellent fun.
@Skidder still getting wet in your Kayak?
