Welcome, Mark. Yiu have just bitten off as much as you can chew, and chew, and chew...
I started my collection last year, jumping in with both feet. Started on eBay and got burned a few times, so I started buying graded cards. I liked the look of SGC, and as a consequence the vast majority f my HOFers are graded. Finally I got clued in to Net 54 and now my focus is on fillng my set with raw cards with the caveat that I buy graded HOFers. Oh yeah, I am doomed. Started picking up a few Backs here and there, marked cards from prior collectors, oddities, miscuts...it s so monstrous

that I recently unretired to pay for this bad...err, Newly acquired sophistication

.
Oh yeah, some of the threads can be entertaining as wel as informative.
Good hunting!
