Hello IG,
I have a Sea Doo GTX Limited. It is a 1999, and is a 3-seater. I recommend a larger jet ski for a few reasons. One is that it will handle better, and is easier to board both on the dock and in the water, as it is more stable. Another reason is that in NH, a jet ski with more than 2 seats is classified as a boat, which means that you could use it on a body of water that jet skis are not allowed. You have to get a special sticker from DMV for that. All the 3+ seaters have tons of storage, I know mine does. No PWCs that I know of have running lights of any kind, and are restricted to daytime use only.
I believe all the manufacturers offer a 4-stroke motor, which are much easier on gas than the 2-strokes. I would go with that if you can afford it. Personally I own a Sea Doo, and 3 friends also own Sea Doos (same size) and none of us have had any kind of problems. I have another friend who has owned 2 Kawasakis, and had no probs with either. I know one person with a Honda, and has had no probs. I do know of someone who owned a Polaris and had mulitple probs. That would be the manufacturer that I would avoid.
If I can answer any other questions, please let me know! I could go on and on with this subject!

Chip
BTW, I love mine!!
