i sold my Mfd2 on ebay 3 months ago for £346.
Bought a Rns510 for £480.
Both myself and Stealthwolf have bought from the same core seller on ebay, hes in the top 1000 rated sellers in germany. Expect to pay £699, that will get you a newer Version B. If you Pm Stealthwolf from here, he has the sellers name to message.He replaced my Rns with an issue no hassle, even though he sold it to my seller 6 months before!!.
great service imo.
Great unit, makes the MFD2 look 2nd division.
