The Phazer is a great little sled that handles well for the beginner rider or smaller riders. It carves very easily, easy to ride down the trail, comparible in weight to 5 and 600cc size sleds, awesome on fuel and cheap to own. With that said its a very rider forward sled, personal preference if you like that or not but most do, and 80hp isnt alot but plenty for most beginners or smaller people.
There were a few recalls on the early 07's but were easy little fixes like, ball joints, snow block off and ecu update. Like you mentioned, there is alot for sale and usually can find good deals on one. My gramps has one with over 17k miles on it and still going strong. If you do decide on getting one let me know and i can run the vin and do any and all recalls that are applicable to it. (free to you)
