Personally, I'd like to see an array of effects, that you can pick from. Sure, the Rom's and Klin may only have 2 maybe 3 each (as theirs tended to stay fairly constant), But I think it'd be cool to be able to pick from TOS, TMP, TWOk, etc etc, and as well, the beam out animation itself, be kind of cool to flip out a TOS communicator, and then beam out, instead of tapping your chest.

Honestly, I'd just be happy if they'd change it so the transporter effect is based on what ship is transporting you rather than your race.
I like the idea of having the transporter effect based on the player's ships. Players flying Fed/KDF/Rom ships would have the Fed/KDF/Rom transporter effects respectively, and players flying lock box ships could have the lock box ship's race's transporter effects as well. For instance, a player flying a Breen ship would have a Breen transporter effect, or a player with a Jem'Hadar ship would have a Jem'Hadar transporter effect.
