Negative on the bigEZ, way to big for your size and weight. I can't comment on the other two choices as I know nothing about them.
I can say that I am a little taller, 5'5" and 140lb, and I have a hard time with any kayak that has a lot of volume in the front of the boat. When the kayak has a high deck up front, it is an impediment to getting ones arms into the proper position for rolls for us vertically challenged. So I look for kayaks with lower cockpit decks. I currently have a EZG45 as my river runner/playboat and a Microbat 230 as my creeker. I would not suggest any boat over 65gal, which is the volume in my current and last creeker. If you get a boat more suited to your size, you will progress quicker.
I started in a Euro-kayak Cipher back in 92 and it was the worst boat I could of bought for my size. That boat had 78gals and I fought it for two years before I wised up and got a Wavesport Micro-x (65gal). Once I downsized my kayaking came right around. Now I have a 28gal, 45gal and a 65gal kayak in my quiver.
As a former Zip owner, I'd highly suggest the Id- especially at your size. The Zip is a wide m'fer that's hard to roll. The Id's size is much more friendly for your frame, and will be easier to roll. The Zip is a good ocean / surf boat, though.
If it's in good shape, I probably would buy the Id.
The Id was my first playboat and there was a lot good about it --
From a river running standpoint, it has enough speed that it does quite well in class 4, even very big class 4, ..
AS LONG as you can deal with the fact that it is VERY slicey. You have to have very good edge control to keep from getting caught by cross currents and window-shaded.
I think this boat can teach you/train you to make really crisp eddy turns and watch your edges when you change directions in rapids - cause if you don't, you'll get chundered.
As a playboat, you know it's definitely not full-on. It's a bit long for looping, and many new-school hole tricks. Volume distribution is wrong for real aerial play.
But it has a very loose hull for a boat of its length, and surfs and spins really nicely on the right wave. Also, being so slicey, it is really good for flatwater cartwheels and is a stern-squirting machine.
Being an older boat, it will have harder/more durable plastic than current Dagger boats. My Rx isn't holding up nearly as well as my old Id, which I regret having sold a couple years ago.
But if you really want to playboat, I would buy a newer, shorter boat.
$200 for an Id in good shape is good deal, though, IMO ...
