If I were in the market for a new system, I would probably buy an EcoS. However I would look very carefully at the CT Elektronik ZF5/HR3. This has a very impressive specification with a wireless option and a competitive price. The hand controller has a solid feel of quality. I have not seen any reports on how good in operation and how reliable the system is, so it is something of an unknown quantity. The firm is noted more for technological innovation than good customer communication, but the system is sold in the UK by Digital Supplies and Digitrains, so you could ask them about the merits of the equipment.
