     I guess I like simple stupid and common.
     If the parts are at radio shack... thats indeed common.
     I use a IRF510 fet $1.99 at RS.
     Bias it into the linear region and then use a passive R splitter.
     Roughly 10K to Vdd
     Doesn't get much easier then that.
     I also will put a tank circuit on the drain and tune it if I want to
     make a square wave into a sine wave. Use caps to isolate dc...
     By the way I do also use Grassvalley video DAs and other broadcast
     DAs with the clamping turned off. They easily go to 10 MC. But they
     draw a bit of power compared to the simple fet approach.
     Regards
     Paul

     A friend of mine is looking for an inexpensive way to distribute
     his 10 MHz T-Bolt signal to other instruments. The TAPR unit, while
     very nice, is a tad on the pricey side when you add in the
     enclosure.
     Any ideas what he could use that is not so expensive ?
