difference as in; the difference between the 08' and 09' Kingman Electra is the feedneck. The 08 model uses a twist lock style feedneck similar to the VS series, while the 09 model uses a clamping style feedneck similar to a CCM feedneck.
i think their the same exept for the feedneck and they switched the sides the hose plugs into.
if it were me i would prolly just get a 09 for $30 more you get a newer gun, i dont know if there were any bugs in the electra at first but if there were then they would prolly be fixed in the 09 model.
If the clamping feedneck looks decent then get the 09, simply because they *hopefully* fixed any issues the 08 may have had. Otherwise I'd say go for an 08 and just buy a nice clamping feedneck, it would probably cost you the $30 you saved but I doubt Kingman's is too great...
