Air tight Contracts

I am told that Louis Brown has the best forms/contracts in the REI business. Is there any truth to this claim?

I am looking for the best RIE contracts out there. Can anyone tell me from where I can obtain them? I am looking for them all, Lease Options/Purchases, Promisary notes, Addendums, Leases/Rental Agreements, Contracts for Deeds, etc. If it is for REI I want it. Of course I will have my lawyer review them for their validity in my state.

Anyone got any ideas/sources?
