Hello Bill....
At $450 thats more than 1/2 what it cost new...so right there its a deal....but what are your plans with it....as far as a recreational boat...there a lot of fun..toss it in the car and have something to do on the weekend or vacation or whatever...they have a clutch and water pump that makes then very user friendly.. The reviews are mostly good with only a few negative points..but I think thats mostly user issues...and a lot of youtube videos on the boat...so its a new boat...just way less than new on price...
