If you were going to stay with Whites there are only two machines that I would consider in the line up mxt all pro with 6x8 sef coil and Mx7 with DD coils.I have the mx sport didnt like the tones at first was getting ready to sell then pop an 1861 seated dime in iron how can I sell it now.Between thaugh found a 1900 barber dime and 1908 indian. 5x10 dd coil.I have more time on the mxt than any machine and its hard to beat the machine coil combo mentioned. Still new to the MX sport not difficult to wade programs but the audio begs to be learned and takes time but offers more info than the mxt great depth.I have ten machines and EQ800 on the way not ready to sell any just yet, just my opinion,,,,,CEDAR P.S. The list Excal 1000, EQ800, Tesoro S.T. mxt A.P, MX Sport, T2 C., G2+, CF77, Cscope 6mx, Cscope 4pi, Symplex +,,,,,by the way found my first three cent piece no date with the G2+ last week.
