You are going to go through a few boats until you find the one that you really like. Doesn't hurt to buy the one with the highest chance of resale (Burn).
X2... only the large. I know on the newer ones they have a M or L stamped by the drainplug.
But in all honesty, If you are willing to spend $500 for the boat only I would wait and find a used Jackson 4fun so you can have a little play while learning (or second generation Superstar). I started in a Diesel and got bored very quickly.
