In favor of the v1, it was the first "premium" toy to feature the flush-closing backplate and flush-fitted backpack hinge, along with a lack of external swing bars for the legs. Those were some pretty revolutionary features back in the day. I did always like the weighty feel of those due to their diecast content too.
That said, I'd give them a hard pass in this day and age. All of the v1's (good) features have been adopted and refined considerably by subsequent lines. This specific example is probably worth no more than $20 as a parts valk. I sold all of my v1s several years ago and had sold the Super-equipped valks for $65 a piece, boxed and complete in good condition. $50 for a broken one is wack.
