It really depends on how you want to use it, but for my wife and me, the inflatable Skedaddle tandem from WM is great. We don't need to go grocery shopping, so it's just to get from the boat to the shore when we're visiting on longer weekends. It has some storage room, so you can wrap up a change of clothes in a large ziplock bag to be more presentable on arrival.
The kayak folds into a large suitcase that fits nicely into the lazarette or quarter-berth, takes 5 minutes to inflate and is easy to launch and retrieve by way of a long polyprop line attached to bow and stern.
We've paddled round-trip to shore, about a half-mile each way, in a stiff cross breeze and it tracked nicely. I was concerned that an inflatable would just be blown sideways - didn't happen.
Got it on sale for $300 and consider it money well spent.
