Yeah, I don't really care all that much unless it's a game I really love, but even then, I usually don't mind. I can think of one example of a second wave that I actually like a lot: the gray Zelda carts for NES. Not sure why, but I love those. My CIBs of Zelda 1 and 2 are the million seller ones, and I actively sought those out. I guess that's one of the flipside examples rarity-wise? I know there are still tons of them out there, but I've actually never seen either gray cart at shops, flea markets, etc. Only online.
