Build one. I am currently in the process, using a mix of designs offered by Pat Warner and Bill Hylton in their excellent books on routers. I won't be using a Festool to power it. 
Commercial tables might offer an advantage with the fence. So buy a ready-made fence. The best available are either CMT or WoodPeck are about the tops. I bought my fence from these guys --- http://woodhaven.com/ . It offers the most flexible attachment system. Before undertaking the table, I bought the fence because it can attach to a tablesaw extension table. Design wise, I think noise reduction and dust collection are big issues. Dust collection also preserves the router by circulating cool air if you are running it long and hard.
My Milwaukee fixed base router forces me to get on my hands and knees to change bits. And to do it in the relative dark. So the table I'm building has a tilt top design favored by Bill Hylton in his new edition (don't get the old) WoodWorking with the Router. Oh, and a power switch that simultaneously triggers the vacuum and the router is nice to have. It is an easy project, and I am enjoying myself. The top is 1" Euro plywood, with torsion-box type supports to prevent future sagging.
