You just missed 2 great events. NJ Paddler just had their show not to long ago and Dave Kayak1 just put on a seminar that was an eye opener for many who attended.
First if all don't be mislead by the jargon like fishing machine, tricked out for fishing, ready to fish, etc. Every kayak is fishable to start with. I have a Hobie Quest that has many things to make fishing seem better but in reality my wife's Ocean Kayak, Frenzy, is just as fishable. And more stable too boot. I like many in the beginning had to have all the toys to put on and once I tipped a few times, (Oh Yes you will tip...) and lost gear I realized I had to figure what I really want to take out with me that is teatherded down. It not, can I afford to loose it.
I do have equipment that I do bring along like a fishfinder, but, it is waterproof and can take total submersion. 1 rod and sometimes 2 but they both are teatherded to the boat so I can't loose them same as my paddle.
Si I guess what I am saying is "Buyer Beware", look around, sit in as many as you can, better yet go to places like NJ Paddler and try them out on the water. Call ahead to see if there are any others going out as well.
There are a few on here that have kayaks and will tell you the same thing. Our best advise to you especially for your first boat is to K.I.S.S. Keep It Simple Silly.
If you have any specific questions throw them out there and I am sure in no time they all will be answered.
Good Luck
