There are a couple knock offs that do the job. Not quite as good as the real ones but none the less they are ok. The Bad News.... Pretty difficult too get repaired if needed. If they fail (amplifier 's) they usually take down a good part of the unit leaving you with a boat anchor.
If you have 1000.00 to toy around with The DartZeel is pretty cool.
