More important may be what is inside :^)

I have built a few using the MCL transformer TMO-2.5-6:

http://www.minicircuits.com/pdfs/TMO-2.5-6+.pdf

Which is small and has excellent performance converting 125 Ohms to 50, 
from .01 to 100 MHz, if you don't want to wind your own balun.

Well worth it these days now everything is 50 Ohms.
