UPDATE: $198.55 here with code PICK5 - thanks to TiLLiCoMe.
The T5 is the newer, faster, better model so do bear that in mind.
T5 500GB - $239.20 @ PC Byte eBay with code PRAWNS or PCTECH. It has been cheaper before.
Not sure if I should've included this in the 250GB post as it is a different seller.
Code PCTECH should also work till 22 Jan.
Wouldn't this be slightly cheaper with 5% off ebay code "PICK5"
