Well, you need to define good credit. Scores are not necessarily everything anymore...do you have a solid history of good credit? Specifically revolving credit, since that's what you are looking for. Do you plan to carry a balance, or PIF each month. If you're carrying a balance interest rate is a priority. If you are PIF then you might be more interested in perk cards.
While many offer the possiblity of instant approval, whether you are approved instantly or not depends on your credit score, history, income, and any number of factors. There is no way to guarantee instant approval on any card. I've gotten instant approvals from most of the big banks--Citi, Chase, Cap One, BoA. Others may have applied for the same card and not gotten instant approval.
