I bought the modified controller from user nicolas_persijn on eBay, he does a really good job and offers them in many styles. You can talk him down on price a bit (best offer). I do like the 'rear model, non click' version the best.
Vector Pilot had a lot of different overlays to choose from, I wanted the original green one that was initially made but he was sold out, I asked which was the next best and the red one is what I got. I am not too fond of it, but with the brightness turned up on the Vectrex in a dark room it doesn't bother me too much, I can definitely see it being annoying in the setting it was in. I was glad to see the many players using the overlays on a lot of the games, usually when Vectrex's are out for public display there are no overlays. I don't mind mine getting scratched up in use as long as people are enjoying them! Vectrex is still a great system!
I noticed your initials on Vector Pilot JSS or VPM? I love how it saves the high scores!
