Yamaha Silent Brass in Philadelphia?

[chronolith]

I have heard any number of love/hate opinions about the Yamaha Silent Brass system for tuba. I am trying to get a house these days with a basement but I may have to move into an apartment soon.

Anybody in Philly have a Silent Brass system? I would love to try one out before I drop $200 for one. I'd really appreciate it! PM me.

Thanks!
