First you need to see if you need a Pre Amp or not. Pre Amps are used to build up very small signals such as a Condenser Microphone. Some Condenser Microphones I researched had the Pre Amp included.

Pre Amps are very basic devices and anyone of them will do the job, if you need it. If you are using a Dymanic Microphone such as a Shure SM57 or SM58 you don't need a preamp and if you use one you may actually degrade the signal! More info is needed to see if you need a Pre Amp or not.

Bigger and more expensive in not necessarly and better.
