I really prefer a new bike over any used bike. lt Seems like every time I buy used it just needs more cash in repairs. That being said spend the money, if you buy a cheap bike it's easy to ignore it. If you spend over 1000 you'll probably feel obligated to ride it some. can't really say much on the 26 vs 29 debate, I'm sticking with 26 and no plans to try a 29, I have too many 26 inch tires to jump ship even if I wanted too.
