I am a computer guy for a small company. I have recently paid down a
rather large debit (both credit card and automotive) and have lately been
using the debit card issued by my bank to make purchases. I seem to have
developed a bit of discipline- I no longer spend until the card stops working,
so I can probably handle paying off a normal credit card every month now.

The real attraction to credit cards is that I often spend over $1000/month
on computer stuff for work. I get reimbursed for these purchases by
my employer. Right now, I am using my debit card, and essentially
giving them an interest-free two week loan. I know some credit cards give
you a kickback based on how much you spend. What sort of card should I go for?
cash back? I imagine the airline miles cards may give more total value, as
they can probably get the plane tickets at a significant discount.

What sorts of kickback cards do you have experience with?

My credit is 'fair' and my income is 'good'
