Just bought a trumpet for my son, who will be going into 4th grade.

Odd(and annoying) thing I noticed is that there are knock off "brand name" horns going on sale there, i.e. pro model horns (schilke, for instance) being duped and sold as shilke (minus the "c"). It strikes me as odd that this has been going on continuously and ebay does nothing about it. Caveat emptor, but as a former semi-pro musician I know the difference, but what about people who don't?
