I found myself in a similar situation a year and a half ago. I have bought mostly lower end stuff, because I can open twice as much. Can't go wrong with regular Topps. Lineage is a fun product, Topps Chrome comes out soon. If you prefer prospects, Bowman, Bowman Chrome, Bowman Platinum...if you prefer rookies, Topps Chrome, Finest....Over half Topps products are rookie or prospect focused it seems. Anyway, welcome back to the hobby!
