pwc noob - need some info

[hybrid gti 2]

I am a noob to pwc but not a noob to forums as I own a wrx. I went to a shop today and found out i was qualified to buy a pwc. So before just jumping into this. I need some info. I have ridden a seadoo 4tec and a honda 4 stroke. I liked the seadoo 4tec. I am now looking to own something. The shop I went to has yamiha and kawasiki (I know my spelling is off but i figure you understand) I want a stable ride something that can carry a few people and have resionalbe power in a 4 stroke. So I was interested in what you suggest I should look at buying. I also need a trailer and looking at zimmerman I think it is. I figure get a double for good measure. Now I would be towing it with my wrx which currently has a hitch on it. Is there anything else I should know or be thinking about here. Also any suggestions on accesories? life jacket, gas can. anything else?
thanx
