This is one of the better dual tuner freeview PVRs available at the moment. The next brand up would be a Topfield and they cost in excess of £220.
The PVR9200T has a built-in 160GB HDD and 2 freeview tuners. You can record one channel while watching another, record 2 different channels at the same time or record 2 different channels at the same time while watching a 3rd (as long as the 3rd channel is on the same mux as one of the channels being recorded). In addition, it has a USB 2.0 port to allow you to upload saved recordings to a PC.
To get the price down to £163.20, you have to add the item to the basket and then at the checkout, put in the voucher code for free delivery (PRFREEDEL), update the basket (so it shows free delivery) and then input the voucher code for £20 off (PERK20) and then update the basket again.
Edit: changed title from "adapter" to "recorder".
