I got a T&E Mantis X10 Elite, and (finally) finished my review of it:

There's no getting around that it's expensive ($250). But it also provides a lot of value in terms of data that you're not going to get out of a par or shot timer. Not everyone seriously cares about maximum performance, and that's fine, but this is a very useful tool to getting there.
