I cant reccommend a specific make Tony but can offer a little advice that may be of use in the future
Most of the models available at the moment dont have a CAM slot as they arent needed for the free to air programmes and until the recent introduction of Top Up TV there didnt appear that there would be a subscription service again on Terrestrial Digital.
Whether Top Up TV lasts or is worth having or not I am unsure of but it would make sense to make sure that any box that you bought had a CAM slot so that you had the option.
I also think that twin scart out is better than the single scart so you can feed to the tv and your vcr or if youre as rich as Simon and Clive your DVD recorder.
I would be looking for a twin tuner version, havent seen any out yet but there must be some in the pipeline if none about already, because with a single tuner version you would only be able to record the channel that you were watching after they switch the analogue tv off in a few years time
Hope this has given you some food for thought
