If you are looking to do 100hrs, why restrict yourself to one place? Plenty of FBOs all around the US would give you a better deal. If you save only $10 per hour you are quids in! If you want to rent out of S California you should join a club. consider MYF in San Diego. Better rates and no sales tax if you are a member, that will save you 8% off the bat. Head for the mid-west and you will save even more.
Anyway, Rainbow comes well recommended.
