I agree, I think Capital One offers the best deal in terms of a low deposit. I was approved for a $200 CL card with a $49 deposit. But for some reason I also thought that they would give the deposit back after a number of months, but now that I go back and read, they only say your deposit is “refundable”, but when you close your account.
One thing that I do like is that “you may earn credit line increases based on your payment and credit history”, which basically means getting unsecured increases (I’ve already had a $100 increase). All in all I think it’s a great card and it’s serving its purpose.
