One of those "Is this worth picking up" questions

[AtariLeaf]

There's a local fellow who answered my ad for "wanted: atari" games and I'll be stopping by today. He has a few loose carts and some boxed ones, mostly common. He's selling the boxed ones for $6 each and one of the titles turns out to be colecovision - Tournament Tennis. Now I asked about it and its the telegames version, not Imagic (If it was the Imagic I wouldn't be asking this question, I'd grab it and run). Since I'm not a cv collector, is it worth picking up as trade bait? I guess its silly to ask when its only $6 but I've been spending a lot on stuff lately not atari related just for trade bait that I'd like to make sure that I'm not just picking up something that will sit in a box and no one else can use it.
