about $190 for the saddles and the preamp. You need that plus maybe a new pot ($5), and a 9v battery. I don't have, but would recommend, the switch ($20?). So yeah, it's the price of a cheapo acoustic. If you don't have a lot of space in your control cavity, I'd suggest going for those mini pots, they're tiny. If you've putting it on something with a normal fender tremolo or hardtail, you can buy from stew mac, they're a great shop. If you have a tele or non-standard string spacings, etc, graphtech sells the saddles in a variety of shapes and string spacing (you can get them in a wilkinson tremolo format too). I bought mine from musician's friend 'scratch and dent' and saved a bit of cash (it's in perfect shape, couldn't find any 'dents'), but I don't like the way MF packages their stuff at all and wouldn't recommend ordering fragile parts like that from them. The parts were just rattling around in a big badly-taped box with one piece of brown paper as 'filler'! Whoever was trashing MF on this board a while back had a point.
