Kayak fun

I am really interested in buying a kayak. Will be used mostly on lakes, not rivers. I was thinking of getting a sit on kayak instead of a sit in one.

Plus since I fish I was thinking of getting one of these. I am a total novice when it comes to kayaks, but it's something I have always wanted to do and have.

Any ideas for normal recreational kayaks that don't invole fishing? or any info in general would be awesome!
