I have a Dillon alto up on ebay:

I purchased it new from Dillon in July to start learning on. In December I decided to go all in on alto, so I packed it away and got a better horn. It plays really well, I like the response a lot, but the slide is -- well, same as every other Chinese alto. I took it to my local music shop to have the slide worked on, but it's still scratchy. I guess that's the corner you have to cut to shave $1.5K off the price.

Anyway, it's in like new condition for half the price of a new one.
