Assuming you have had them balanced a second time and the problem remains then a problem I have seen in the past is the refurb places put too much paint on the back mating surface - so it doesnt give a flush flat finish against the hub - causing a wobble.. the other place is the centre hole where it mounts - thats easier to spot as they dont go on easy. Post up a pic of the back of the wheel - might be worth sanding them back if thats the case

Gen 7s values are enduring the undistinguished age of being too young to be classic, and too old to be hip An alternative strategy is not sell if a reasonable resale value ain't there. Mothball Moo into barn storage somewhere safe, under a dust sheet with battery removed etc... Revisit in a decade from now - Gen 7s will be far rarer, more interesting, desirable, and most probably far more valuable.
