I would not purchase an autographed Jordan item that wasn't from Upper deck (either a trading card or UDA)
MJ signed an exclusive deal with them a long time back and 99% of non-UDA authenticated items are not authentic
Items non-Chicago Bulls related (golf, baseball, UNC, Wizards) are often cheaper than Bulls-related memorabilia so your best bet will be to get one of those
Unfortunately, all of Jordan’s autographs exploded in price after the Last Dance. You’re looking at around $1000 and up for the magazine or anything similar to that in my experience.
