Remember, you only get those MSDs back at the end of the lease. So if for some reason you needed to get out of the lease, you are going to have to ask the person taking over your lease to come up with $8K and that is nearly impossible.
So as long as you are DARN SURE you will not need to get out of the least, MSDs are ok, but make sure the risk/reward is worth it.
