Im the only odd one here. I love books like Dazzler 1, Alpha Flight 1, X-Factor 1... Been buying tons of NM copies when they came my way for dirt cheap (yup, I bought 300 copies of Dazzler 1 from Koch Warehouse some 4 years ago for $100, they all ended up being error editions). If you have the patience youd sub the best ones, or simply list them for $10-20 and sell them slowly, theres a great market for those books, and although most gave up on specing on them, just look how well New Mutants #1, Punisher #1 (solo), and Spawn #1 did while they were selling for equal prices years ago.
I shy away from specing on books that have already broke the 20+ barrier which are over printed. You simply dont know where they will go and at $20+ a pop thats kinda risky for me.
Wanna laugh? just look how much Alpha Flight #1 9.8 closed a couple of days ago

And on an average youd get 80-130 for it. Now thats a book I love to invest in!
