How hard do you fight for a set you'll never complete

[darkhorse9]

I asked earlier about it being okay to call a set complete without truly high dollar or rare cards included (I'm looking at you 1952 Topps)

I've got several sets that I'm near completing including the Salutations Exhibit set.

I'm just seven cards away from completing it, but that includes the Gehrig ( maybe $1700) and the Rizzo (never really comes up). Every other card I need is well over $300 to get.

I'm starting to wonder if I bother picking up any of those $300 cards at this point. They'd just bring me closer to having a gaping hole in an otherwise curious set. It's not really a set that people buy complete anyway.

So, do I bother trying to complete it or spend my money elsewhere?
