What I have been doing over the last 5-10 years is upgrading the condition of my X-Men run. Nothing graded or in super high probably averages around 7 but that is a substantial upgrade to my readers (I was really a bargain hunter as a kid/teen). I am only doing this for 94-143. That's been a fun exercise and it gives me something to hunt for... always looking for a small fix.
Now for the 1-93 I still pick up beat up copies, I like those to show their age more creases, chips, even an owners name on the cover is fine for these. The main reason is I want to have them in my collection BUT not so bad that I want to pay up for them so a beat up copy of the Mimic's appearance suits me just fine, just happy to see it when I flip though my X-Men box.
X-MEN BABY! SNIKT!!!
