A decent quality decoder at a sensible price. Maybe not quite as good as a Zimo but a pretty good second choice.

I that's the case then that would explain why it doesn't work but neither would it work ...

Just a suggestion . . . Instead of buying a 30 year old design / technology NCE system why not go for something a bit more up to date? Maybe the nèw Signatrak Ace 3 which they have announced is due to start shipping within the next few weeks. The Ace 2 was good but the new version is much improved, ...

To be honest it's probably time to replace it. I'd recommend a Lenovo M10 3rd generation 10" tablet. You can buy them on Amazon for £130-£140. I have two of these which run my Z21 and they are very good indeed for the money. You can also still buy the previous 2nd gen model for a bit less but t...
