I have been paddling this model for several months now. While it is not perfect, I feel like it is a very nice rec boat for the price. To be honest, I wanted to get a Pungo 120 but didn't have the money to buy the boat plus all of the needed accessories. Found this one on craigslist for a nice price and have been pleased so far.
I think it is important to consider your needs when looking for your first kayak. The vapor has a very large cockpit and is fairly wide. This makes for great stability; I find the primary and secondary stability to both be excellent. It is also easy to get into due to the large cockpit. The downside is that water from the paddle will usually get you wet and in anything above class II you are going to get flooded without a skirt. You will also need a skirt during the colder months. I was willing to make this compromise since I paddle with a 4 year old and the large cockpit provides plent of space for the both of us. If it was just me I would probably go with something like a dirigo. I look at this as an all purpose kayak with the strengths leaning towards flat water and class II and below rivers. If you are looking for an all purpose boat that's strength is more in the river department I would recommend something like the liquid logic xp series.
Here is a pro and con list.
Pros:
Great stability. Nice sized cockpit with easy entry. Tracking is very good. Day well in back is handy and the cover keeps stuff dry as long as you don't capsize. Price is reasonable for the quality. Foot pegs are easily adjustable and mine have never moved on me if I didn't want them too. Seat adjusts pretty easy.
Cons:
Turning takes some effort due to longer length. Seat not very comfortable (for me). I find myself wanting to get up for a bit after 2 or 3 hours. Not terrible but could be better. Doesn't track as nice as longer boats. Day well in back not really sealed good enough if the boat rolls. I keep my stuff in a dry bag.
