Thats the cheapest I've seen, I had a good look around & bought one in November.The main problem I had was getting an aerial mounting bracket, I made do with a lump of wood but eventually bought the proper one .. another £15 if I remember. I bought from www.mesltd.co.uk (site takes a while to load).
Can't compete with that, my price is £224 but it is for the dual band version, I don't stock the halfway house one, just the top and the bottom so as to speak.
I suspect your price is from MES and their price seems to be the best. You could always take advantage the ever-so-special prices at ybwstore and pay a 20% premium, taking the price to £250! Still, you do save £2 on delivery charges. But before I get flustered on that subject again, I'd better take another tablet. Nurse! Nurse!
