I've been working on that set for about 15 years now, and I'm about 75% done. It's a low priority for me, but it's tough to find these guys compared to 1939 and 1940, especially at shows. Congratulations on quick progress, and don't skimp on the key Williams or DiMaggio. Patience can find you a solid EX copy for $700 or so for Williams and $800-900 for DiMaggio. But if condition isn't so important to you, they can be had for under $500 each with luck and patience.
