The final hunt is easier than shitting in the bed if you know how to work your paradigms.
It was easy....I just couldn't be bothered with attempting that 30-45 minute rinse cycle with a controller attached more than once in attempts to 5 star it.
Though for an easy way to get the item collector, here are some easy steps: (though i never did it....again, i iz t3h lazy)
1.) Transfer save file to to flash drive
2.) Go to computer and load up save editor
3.) Max munnies
4.) Buy manufacturing items
5.) Rinse repeat till you have enough crap to make everything.
PS. Feel free to write your guide. I'm sure it will help people do it legit.
