sony shop still produce old psp?

At Malaysia, there are many shops selling recorn psp but they tell customers the psp they sell is new psp, so who can tell me how to identify whether it is a recorn psp or a new psp?pls help.... and i not very sure old psp be more better or slim psp..

what do u all think about the new psp ? i decide to buy a psp , but i dunno whether the new 1 better or the old 1? Sony still got produce the old psp??
many people tell me old psp is better than the new 1 ,because the new psp spoil then we need to change the whole motherboard, and the cost is very high, In other way, the old psp spoil then we onli need to change the chip and it is much cheaper.
