$300 budget for 1st MD

There is a Pirate Pro on the for sale section here on the forums here for $200 and they are a great starter machine.

total cost approx of course but best setup would be (in my opinion):

used fischer f2 OR ace 250 - 150$ (wait on the right used one and u can get a sniper coil thrown in)

new garret pinpointer - 100$ (new one would be very nice but used is also an option, they are tough)

garret digger or lesche digger - 30$ (new once again nice, used doable on garretts but lesches maybe not)

280$ with enough wiggle room to allow for shipping
