Please note that this is the PLUS model, it comes with a multimedia remote and has a quad core CPU rather than the dual core that the standard TS-451 has.
currently on back order, but it should ship. choose cheapest shipping, pay with GBP and use a credit card with no foreign transaction fee. should be around $340, depending on how your bank converts the currency and any fluctuation of US/UK currency. if your card charges a fee for purchasing with currency other than USD, it might still be worth purchasing with USD and taking a 3% conversion fee because amazon charges about 5%.
in the US this thing sells between $450-$500. it should ship as i bought this exact unit at a price even lower than this from amazon UK/DE a few times before. it do IT work for more than a dozen companies, i buy these all the time for backups/DVR/file servers/running Unifi server/etc.
DEAL IS DEAD as of 11/25. price has been corrected. sorry
