Hi Bezza. I've used the homebrew shop lots, and found them very good to deal with.
They have a very good price on the bulldog brewer, and this may be an all in one option to consider. I have one and am very happy with it.
I did have a problem with the pump, but the homebrew shop replaced without quibble (I subsequently got the other one working, so have 2, but don't tell them!)
You could use the second pump to circulate iced water from a bucket through your chiller during the summer months.
