PSP GO Only Taken Out Of The Box To Check If Everything Is There and has been turned on to see if working For My near New 30Gb Zune that cost me $200 and i only used once and then just keep it in its case and not used
he is selling it for 170NZD and he said its only been powered on then he put back in box because he already had one and he won this from a radio comp
and it comes with
512Mb Memory Stick
4 Games (Ratchet and clank size matters, Transfomers the game, Aliens vs Predatos- Requiem, Sims two castaway)
1 Movie ( Anacondas- the hunt for the blood orchid)
In my opinion, The real question is if you would use the PSP Go or would it just sit in its box/case too.
If you won't use the PSP Go you could try to trade your Zune for something else you want or need that you would actually use..
It is very unlikely that you would ever be able to sell a used Zune 30GB for anywhere near $200 you would be very lucky to get $100.
With that said...
If it was me, I would make that trade because you can do a lot more with the PSP Go than you can with the Zune.
Also, I collect videogame systems, I don't have a PSP Go & would use the PSP Go more than I would a Zune.
