was looking to purchase a l&r for my one of my tc renegades or is their something better out their for the money.
Short answer. No.
L&R makes a number of period correct locks depending on the build. All the quality that goes into any of them is present within the RPL.
Given the inlet is already positioned, if you attempt a different lock you will end up with inlet issues with both the lock plate size/shape and possibly even the trigger mechanism. More headache than would be gained.
I have a L&R lock on one of my renegades, and while it has some nice features such as the frizzen to pan fit and a roller on the end of the frizzen that contacts the frizzen spring, I don't think it is any more reliable than my original TC lock and I definately get better flint life from the TC lock. Don't take this to be a complaint about L&R it is a nice lock and I don't regret the purchase, just don't want you to be disapointed if you decide to buy.
Just my experience.
I did complain to L&R about poor flint life and they had me send it back and they changed something and whatever they did improved the flint life some.
