With the Valentine One you will find they only do these back at their one location in America. This is a service they charge for to change the hardware on very outdated units usually older than 8-10 years.

You will also find that the V1 is a very solid unit - I still use my revision 3.864 model which is 4 1/2 years old and works just as new. Since then they have come out with the 3.872, 3.891, 3.892 & latest the 3.893
