Should I sell my PSP 3000 on Ebay for PSP GO?

I have Had my PSP for 4 months. It is my first psp. Also i don't have a massive stake of UMDs i only have one Kingdom Of Hearts Birth By Sleep. I have beaten it so i don't really mind the lick of the UMD Slot on the PSP GO. Sony announced a few weeks ago that they will stop making UMDs. They are selling the stock they have. if you dont own a psp dont bother answering. Should I sell it on ebay.
