I would love to happen upon a deal for a run of Topps factory sets, but frankly, I would never pay anywhere close to what I have seen them listed at. It's hard to justify $50+ for a basic set. I feel like they had to resort to inserting things into the sets for people to even want to buy them. Leave that to the packs and price the sets reasonably. Not much will like come from them, given all the update sets they make.
I did buy a couple of those Dodger specific Topps sets from around 2006-08 range I think.
