[Elecraft] Question regarding BL2 250W 1:1/4:1 switchable Balun

[thom2 at att.net]

I was about to order the BL1 balun, but once again have procrastinated.  Is it save to say that if I buy the BL2, I won't be needing the BL1? (Sometimes it pays to put things off!)

> Our highly-efficient BL2 balun can handle up to 250 watts and can handles 1:1

> resulting in an SWR of less than 1.2:1 from 500 kHz to 55 MHz (200-ohm load). It 
> includes rugged screw terminals for the balanced output as well as ground, and 
> can be used in a variety of matching applications.
