The first MMW I ever had was the 1st printing Incredible Hulk from the late 1980s. My grandmother bought it for me for Christmas in elementary school. I still have it in my collection. The last three years I was able to put together a complete MMW HC runs of the following titles:

Amazing Spidey (the 1st volume is the original printing, the rest are the current printings)
Avengers (Vol 4 is the marbled TPB, the rest are HC)
Fantastic Four
Incredible Hulk
Marvel Team Up 1-2
X-Men

At one time or another I had Warlock 1-2, Deathlok, and Defenders 1-3 but sold those a while back. My first choice is always the classic marbled variant covers. My collection is split roughly evenly between DM marbled variants & the silver/black editions.
