So I have an opportunity to buy a used Valentine 1 detector for $150 (it's in good shape). Problem is that it's a 1.7 unit with a serial number of 0823000442. He said it has been upgraded at some-point but he doesn't know what version it has and doesn't have the power cord to check it.
Now I don't need all the latest/greatest features like Euro mode, phone connectivity and the like, I just need good detection. Besides POP mode, which I don't think is used very often anyway, is there anything that I should take into consideration when buying this unit? Is $150 a good deal if I still have to buy the charger/mount and whatnot?
I also have the opportunity to buy a 8500 X50 Red with case/mount/cord for $140, and I've had one before, but I know that people swear by V1 and would like to check it out for myself if that is a good model/price.
