I think I bought one of these horns when I first started (if its the same manufacturer, looks awefully familiar though), cheap is right, and cheaply made. I ended up putting a new end plug in it as the factory butt had 1/8" gaps in it. Not that its a big deal, but when you spend money on something you shouldnt have to do that. I think they were made in India. Looks pretty similar.
I used to buy alot from SG, but their shipping was always so high.
