Question for any old-school MK "experts"

I have MK Trilogy and I recently found online someone local who is selling some PSOne games, one of them being MK3. As a collector I am compelled to buy it, even if he is listing it fairly pricey ($35 if I remember correctly). However, since I already own MK Trilogy I'm thinking this is probably a pointless buy. I know the differences in all 3 versions of MK3, so...basically anyone have any opinions one way or the other? Buy? Pass?

No, it isn't worth that much; I've seen it at used game shops for $10 to $15.

both MK3 and MKT are very cheap and common (at least here) in their PS1 forms.

Yeah it's not worth that much as it's really common. The thing is that MK3 is a lot more balanced than MKT, MKT is good for messing around with but whenever I play it just feels like whole game has just been hacked together with scraps from every MK game and it just feels weird.
