Before I saw the brand on Bid the only place I have ever seen it was in the local cash converters & Ebay, I did days & days of research on looking up all the different tablets before I made the decision on the one I wanted (Toshiba) & the Imedia brand never came up once. Maybe they are a new brand. One thing I have noticed is many companies are buying cheap China/Japan made tablets & rebranding them to sell in the UK or EU, im not saying thats the case with the Imedia one but its definitely worth looking into before you buy any brand that pops up.
I see the specs are:
Brand : iMedia
Model : DGIMTB902
Operating System : Android 4.2 Jelly Bean
Display : 22.5 (9'''')
Camera : front and rear
Internal Storage Capacity : 4Gb
RAM : 512Mb DDR 3
Micro SD Expandable : Up to 32Gb
Connectivity : HDMI, USB, Headphones
CPU : 1.0GHz Dual Core
Wi-Fi Enabled : Yes
Feature : Screencast 2.0
Personally I wouldn't buy the tablet because of the CPU (Would want to know which CPU) & Ram (Not enough for my liking).
