They tried to get me to get one too, instead of raising my CL.
Be aware that no matter how the lender reports a line of credit to the CRA's, the CRA's very (very, very) frequently report it as revolving credit. With this line of credit being unsecured, it would most definitely be treated as revolving, IMHO. So if you get a $30K line of credit, for instance, and you put $27K on it, it will be treated for scoring purposes as if it were a maxed-out CC.
Doesn't mean you shouldn't get it, just realize what it might do to your scores.
