The ETS is very good i was able to get one from Adrien at Public Peace but that was some years ago, I also have the Nova on my S Martyn and it seems good but its still brand new, just had it set up so will see later today what the tech has to say about it.
My now-gone Frog had the ETS hardware...the newer Cazpar has the WSC retainer and tuner / monorails or so sayeth the build sheet. As I've mentioned elsewhere, the newer Nova tuners are a vast improvement over the originals...they were a deal-killer for me.
