The Zodiac is VERY nice. Fun, and forgiving. That's the boat that Ornella pictured.
The ones shown in the link by Erin are generally (around here) called "John Boats". They're basic, and usually aluminum. They're used for fishing, waterfowling, etc.
They had them on sale here last year at WalMart for around $600.
I'm not sure about the boat you linked to. But, if you'd like to stay in that price range, perhaps the aluminum John boats would work for you.
