Took me about a month (maybe longer) to go through the process of becoming FULLY qualified for reserving an audit. It's not quick 'n easy. The $25 background check is the easy part, mine cleared in less than 24hrs.
There's a lot more involved than just paying the $25 background check. Only you can decide if it's worth it. Due your due diligence and use the search function here. How long they take, etc... has already been discussed. Have you taken the time to read through the 54 pages of Audit guidelines?
