in my opinion, if you are a first time PDA user then its a good idea to get a new set so that if any problems occur you can always bring it back to the shop, but if you are a seasoned PDA user then its up to you weather you want a new one or a 2nd hand one...it also depends on what condition the 2nd hand model that your have your eye on.

Just my 2 cents

yeah he means Dopod 838 Pro...but Try to take a look at the O2 Zinc..the both is about the same price..but for those 2 its kinda hard to find a brand new set.

just my 2 cents
