I have a VPC T50 with grip and a Throttle.
Both are the first versions of each type.
No, it's wasn't cheap, and there's already a mk3 version, which has now added some more buttons and an analogue stick.
I did have an issue with one of the boards, and VPC simply sent me a replacement board. Unscrewed the top plate, changed the cables and jobs a good un'.
In use, it really is MUCH more precise than my old CH unit (which suffered from jitter on the throttle axis), so it's massively easier to be precise during say A2A refueling.
The other buttons are nicely weighted and it has a lovely feel to it.
In short, I'm extremely happy with mine.
