I picked the 48 Bowman because it is something I am considering pursuing. It's a small set with some really nice cards in it and they can all be had in the raw form for a reasonable "won't break the bank" price. Musial and Berra are probably the most expensive and Musial can be had for around 300 for a nice one.
Looking for Nolan Ryan and Evan Longoria.
Also interested in HOF autos/relics and vintage HOF cards.
