Again I don't know the full situation, but the thought of having 4 dfifferent cards/banks in my life makes me cringe. I still bet that my general spending and cash savings gets me to your $1000 mark, and even if not my the value of my time and not spending it dealing with card companies and thier associated risks and headaches more than makes up the difference.
Really not much to deal with if you are disciplined. The risks and headaches that you refer to are user created. Use the card and pay the bill at the end of the month....and there are no headaches.
If you combined the cash back from the cards ALONG WITH your general spending and cash savings, you would be at a $2,000 mark.
Using the cards correctly can be financially beneficial. But, as some have said, doing it without the discipline of paying everything off every month could be a huge mistake and tragedy.
