Thanks for the welcome and words of encourgement.
You are quoting the prices of the 533Mhz version which Acube have discontinued, it is not available anymore from them and we cannot get hold of it. Acube have told us that they will not make any more 533Mhz versions and cannot sell any.
They now sell the 667Mhz version (which is the version we sell) for £440 - (465 EUR+ VAT) - we sell the exactly the same 667Mhz version for £439.99 - our pricing is entirely consistent with them.
We do not inflate any prices. We sell at the manufacturer's RRP.
