Can work out to £101.44 with cashbacks.... see below:
Comet Accessories have the 1TB Buffalo LinkStation Live (LS-CH1.0TL) NAS drive for £119.99 which is the best price I could find online at present, but also have a discount code for 10% off (WELCOMET10) which brings the price down to £107.99.
Also, if you use Quidco or TopCashBack then this works out to about £101.44. Great Price for a 1TB NAS.
This Network Storage allows streaming to PS3 and XBox and also allows web access which you can get to from any PC or iPhone and can also share files with anyone you want to give access to.
