Dillon's has one that is slightly used that is much less than the 8700 price that you mentioned (at least they had it recently). It plays quite well...if you are familiar with the general sound/playing characteristics of the 2155 and you like it (assuming you do), this horn is good enough to buy "sight-unseen"

I bought my 2155 from them last oct and am happy still, this one is almost identical to mine.
