If you're going to buy a Chinese made tube amp this would probably be the one to go for: http://www.bogneramplification.com/index_alchemist.html

In cahoots with Line 6 over more than just the Spider Valve it seems.
Bogner has designed a small line of amps that will be available in the late spring. These amps are being built in the Line 6 factory overseas and they're being distributed through the Line 6 dealer network. However, they do not say Line 6 anywhere on them, they only have the Bogner logos.
Bogner Alchemist 112 40 watt 1x12 - MAP $999.99
Bogner Alchemist 212 40 watt 2x12 - MAP $1099.99
Bogner Alchemist 40 watt head - MAP $899.99
Bogner Alchemist 100 watt head - MAP $1099.99
The amps are 100% all tube and are 100% being built under Bogner's supervision.
