I have become interested in watersports.  Do you like it?
I do like some of them, but I know there are many. What kind do you like?
I was thinking about wakeboarding or kayaking.  Which would you recommend?
I don't know much about the water sport of wakeboarding, but I do like to canoe. I think that's similar to kayaking. 
Is it expesive to buy a canoe?  Is it hard to do?
I didn't think it was hard to canoe, it's a pretty easy and relaxing water sport. It actually is an Olympic sport too, first started in 1924
