Mooh- Check the catalog section of Pick-Up the World's website. The prices are there. Mostly $110, except for multiple and stereo systems for the studio, and on very large instruments such as the Grand Piano. On the mandolin, they're placed outside, either on the bridge or just behind thebridge. You said, "I'd like to get rid of all external stuff". If you mean you want a pick-up mounted internally, I think that would be pretty tough for ANY kind of pick-up, for the mandolin, unless you're willing to pay a luthier who may have to remove the top to install it! BTW, I'm probably the only Mudcatter who has ever heard of Pick-Up The World, because it's a local company, and is brand new. But I truly believe there is no finer pick-up made today, and certainly none anywhere near as versatile. Check out their web-site further. These things are truly revolutionary. BlueJay
