Hey Boot!! I think you are trying to purchase the old one?? Am I right?? Sorry to say this!!
But even if you'll be able to purchase it then after few months it would be really difficult for you to repair it and all, so instead of this why don't invest a little now so that to have a happier future?? I know it would cost a bit more but the thing is you'll not have repair it again and again !!
Lastly the decision is up to you!!
