I actually didn't own a physical copy of Uncanny before 281, only digital, outside of some old early 90's TPB's (Dark Phoenix, From The Ashes, Asguardian Wars, God Loves Man Kills, Days of Future Past and Present and X-Tinction Agenda.) I thought I would fill in some of those missing gaps but I'm not going for everything. The first appearance of Gambit is expensive EVERYWHERE. Getting some of the newer Omnibuses would actually be ideal just because the paper stock is higher quality.
I am finding the way people grade comics online is exactly like how they grade Vinyl, they're straight up lying about the quality.
