I am quite sure that MP 4 is much more easier to find than MP7.
I still remember there was some hype about MP4 when it first came out as Starlord was targetted to become the next one for Marvel. Unfortunately, it didn't turn out that way as he was pretty well gone after only a few one-shot issues.
I actually liked Starlord and cherry picked 2 or 3 issues of MP4 from the newsstand when it first came out. Spent the past weekend looking for my magazine box and for the life of me, I just can't seem to find it in the house. I know it's in there somewhere along with all of the Rampaging Hulk's, Savage Tales', Savage Sword's, Heavy Metal's, etc.
Maybe I'll take another stab at trying to find it sometime this summer, but probably not worth the time or trouble that it would take.
Now I don't know what you have to deal with to get them out, but there is a high chance that it is worth your time. Especially if you cherry picked them off the Newstand.
Raw issues in "newstand"ish condition will net you $300+ easy. CGC'd 9.6/9.8's will get you $600+ easy.
Well, maybe I'll be lucky and won't have to do anything as my wife is in the midst of pulling out all the boxes to sort out her clothes for the new season. Maybe she'll find my box for me!
You could buy her some new Prada Pumps with those MP's
