Brasswind:
These guys seem to have the better quality chinese stuff. Mainly in the form of a 186 and 191 mirafone look-a-like.
They also have "Barrington" tubas. These look interesting from the picture. They really don't look chinese, but who knows? Smal tubas however, but pretty darn cheap.
Custom Music:
Well they do show the new 4/4 york copy as a horn for sale in the tuba rag. Of course what the factory labels the GR-41, they call the PT-606. These guys are crafty

This horn looks interesting. From the photo, it seems to be using a lot of Meinl Weston parts, namely the valve cluster and some of the bows. Might be a decent choice, but probably too much damn money.
My prediction:
In about 6-12 months, the Besson 995's are gonna be floating around for sale like 2145's and 2155's are right now. In about 2-3 years the same with the new Mirafone CC's, not that any of these horns are bad, just the way things seem to go...
