Worth noting there is a new GMTII whcih I discussed above. The older GMTII does not have all of those features and actually looks more like a sub.
The original GMTII is now discontinued and replaced by the GMTII. The older GMTII looks more like a sub as is less flashy but if you want one, move quick before they all disappear!
