I've use the W9XT Contest Card for many years and been very happy with it.
It is, however, an ISA card for desktop PCs. Gary has an external keyer now,
the VK-64, which is a combination voice keyer and CW keyer:

Another popular option with HF contesters is the ZS4TX Super Combo Keyer.
It include CW and voice keyers, as well as some switching hardware for SO2R
that might be useful with multiple VHF/UHF rigs, too:

A third option might be to use a RigBlaster or similar soundcard-to-rig
interface hardware with a soundcard-based voice keyer. Some logging programs
have the voice keyer through the soundcard logic built-in, others run
separate programs. All require some sort of interface hardware (there are
several competing vendors) to use effectively.
If you do want to go with an MFJ external voice keyer, there are some links
on the TR Log web site to hardware interface tips that help overcome some of
the RFI problems with those keyers:
