Also depends on cost and how much your willing to spend. One of the best solutions I've found so far after months of research is the RTI or Pronto TSU9600 (Been told Pronto is going bust.. true or not?!).

However both dont support customers and you do need to be tech savvy. Someone on here I bet would be more than willing to program one for you at an hourly rate of £30 and they could be all day on it at that!

OR

You could trace some Cat5 network cable with an IR blaster and use Harmony one! Probably the cheapest route if you can get it to work!
