I've been away from this thread for a while - wow, lot's of posts to catch up on!
I wanted to pop in to advise an update - Matrix now has an official distributor covering the USA. HERE is a link to their website which is matrix-digi-usa.com
Orders will still ship from the factory in China but any type of technical support or return shipping for RMA will be handled by the local agent in New Jersey. This is kind of a big deal in my opinion, because return shipping on stuff like this can be rather expensive. He is also a native English speaker which is helpful.
No disrespect to excellent sellers like Jeffrey Tam or wsz0304 from eBay - those folks have done a great job supporting the brand and many of us have had positive experiences with them. But as Matrix expands they are starting to have dedicated distributors for certain parts of the world. That's a good thing in my opinion.
Welcome back dude, and thanks for the info
