What type filter

[mmarkase]

I am looking to purchase a new filter for my 55g reef tank. What should i look for and how much should i spend. My local fish guy says the olny filter i should consider is a wet/dry. Thanks for the help.
MM :help:

I have about 60pds of live rock in my tank. Should the filter really matter?
