I have a 983 that I bought in either 2003 or 2004. It was a "dent and scratch" horn at Dillon's...I believe they had about 3 of them at the time, 2 silver, 1 lacquer. Immediately after I bought it, I had Matt Walters do some tweaking. I've played a few of these before (and since) and I can honestly say, in what is probably a completely biased opinion, that mine is one of the good ones.
I love this horn. It's a shame they aren't making them right now. Hopefully, when they come back to market, they won't be too drastically changed. These instruments have such a sweet, velvety sound, and I'd hate to see that quality lost. Everytime I start fantasizing about getting a contrabass tuba again, I play my 983, and remember why, when faced with only being able to afford one horn, I sold my big horn and bought the Besson.
