I have bought (and sold) numerous Decware amplifiers in the last several years, no waiting, just being quick to purchase when seeing one for sale.
Lately too many are asking ridiculous prices.

Having said that it is hard for me to understand why anyone would put money down for a 2~3 year wait.

2 local guys did and both were purchasing their first tube amplifier with zero experience (caught up in the hype), one sold his Torii JRv2 a few months later, not sure what the other one is doing now as he ended up with 2 UFO's because bought one from a friend of mine during his wait.
