After several weeks of checking specs and watching endless you-tube videos I opted for the Roland TD9-KX2 as it was in my opinion the best mid priced kit available for the money. My original budget was £1k, but with 'mesh heads' and a 'real hi-hat' it was well worth spending the extra dosh.
I placed the order on-line just after mid day and it arrived about 24 hours later. It all worked straight out of the box without any set up problems or trigger issues (one of the main reasons why I opted for Roland).
Just one minor gripe - the metronome cannot be routed away from the main outputs, it would be nice if it could be routed to the headphone outlet only. Perhaps Roland can address this issue in a future software update. If anyone knows of a way around this I would be very interested to hear from them.
Apart from the metronome issue - excellent.
