I have heard the Etrade is quite slow with updating shares in r/s though I don't have experience with it myself.
I have both scottrade and fidelity. Scottrade historically has been extremely slow for me (4-6 weeks), while this is my first r/s with Fidelity and my shares have already converted and are traceable today.
It all depends on the brokerage and when they receive the certs from the TA I guess.
