It's the best set ever, IMO. Ever since I saw (and bought) my first T206 in the summer of 1991, I was hooked...my interest and passion has always been rare backs.
If that interests you, you could start to acquire some of the different brand backs, then slowly add some of the series variations, then factory variations, etc, etc. Then upgrade the backs, better condition, better players/poses, etc. It's fun. My son has really gotten into them also.
Good luck.
Here's my rare back "run"...
