And that's why I stopped collecting physical comics in 2007. The Marvel Movie-verse is a much cheaper investment.
There are plenty of good high quality comics that you can buy without being forced to buy other titles you don't want to get the full story. Sounds like the crossover madness of Secret Invasion is around where you got turned off and I don't blame you. I would encourage you to check out some of the current Marvel titles, it's possible to enjoy books without having to read a bunch of crossovers. I manage to do it.
