I think that if it is a model you could see yourself using for EDC, I would say use it.
If it isn't something you would carry, then move it along to someone who perhaps needs that model to fill a empty slot in their collection. I don't really know, but that particular model doesn't strike me as having a large collector following. So I'm not sure how much profit you could flip it for.
Strictly my opinion, as I don't really collect either, I usually just get models I think i may carry. Or as backups for my EDC since down the road I may lose it or something and want a replacement on deck.
