We have not rented from L & M, so I cannot give you a personal experience. But if all the negative experiences posted by peopke on this board scare you away, here is another alternative.
Since L & M is typically the lowest, we use them as a baseline and then bid below that on priceline.com. We specify an MCO car rental agency, and we have gotten Avis twice and Alamo twice, always for a rate below L & M.
