My opinion -- wait for 2 or 3 years, and then check the temperature again. Chinese tuba development can move at a fast pace, and 2 or 3 years makes a lot of difference (as compared to something like a Miraphone 186, which is just not going to change in the next 2 or 3 years).
For example, Wessex is constantly making improvements and announcing new changes and new models, at a very fast pace. Compare their "186-style tuba" of today to one from a few years ago. I understand that the valve linkages are more solid now, the z-valves are used, etc. I'm not saying that the older models are "bad," but if you keep being told that the new ones are "better" or have fixed previous issues... why would I want to buy or try an older one? Or rather, if you want to know what a Chinese tuba is like 2 or 3 years from now... you'll have to wait and ask about that 2 or 3 years from now.
Also, if you're looking at 2 or 3 years, start a savings plan to put aside some money and work towards that goal. If you can set aside $20 per week, every week, for 2 years, then you will have over $2,000 just like that. If saving towards a tuba is a priority, then this should be fairly easy and rewarding to see your "tuba fund" grow like this. Just put the money in the bank, not in your sock drawer!
