How skeptical are buyers towards 60 day locks & lesser-known registers?

Those who have made sales before the 60 transfer lock had expired, what’s your experience with telling the buyer they either must make an account with the register that the domain is currently held at, or, they must wait until the 60 day lock has expired to allow transfer to the register of their choice?

I’m thinking about registering all my future domains with namecheap has they have the best prices. However, I’m wondering how buyers react to making an account with a company they’ve potentially never heard of.

I plan on telling buyers that transactions will be made through Escrow Domain service for added security and trust. So that will hopefully put buyers at ease. But what of the other factors?
