I already knew you were at 520 as I noticed it posted in one of your threads.
But I didn't know you had just made it--Way to go!--

Myself, I stopped at 518 [don't want to pay more than a thousand for any card in my collection] but have been diversifying and upgrading for the past few years.

It took me close to ten years to complete it, and I much more enjoyed the chase than the accomplishment. My first T206 might have been my favorite Brooklyn Dodger, a Nap Rucker portrait. I picked up my first dozen or so while starting a hall-of-gamer collection with my son, going to card shows in the early '90's. Those shows were fun and a good time for us together.

Got back into it after I discovered ebay, starting the Monster quest about 2006, randomly getting a couple hundred at $10-$12 a card.
Finally joined Net54 in 2009, started to learn about the set, and started "climbing the mountain" in a more organized way.
I've probably upgraded/diversified 450 cards over the past couple of years, and I continue to actively enjoy it.

One of the best parts, of course, is transacting with collectors like you, getting to know good people.
Vive Net 54!
