We do use Teradici. We have less than 200 virtual clients, so we have recently started using the free version of 3.0. There are a lot of limitations to using the free version. You cannot schedule, use auto config, or auto find your devices. However, for us, since the only time we use the actual Teradici manager is when we get a new device, this is not a problem. We run two servers to manage our devices, (the free version only allows 100 devices per server). The system still works about the same, but is far more stable (especially since we no longer have to downgrade our devices to connect to the manager). The installer for 3.0 is the same whether or not you are using the free version, the difference is that some features are disabled if you do not pay for them.
