Probably depends on the frequency ranges and such.  The commercial 
transformers are very small, and probably have more consistent properties.

Sure.. it's a trade time for money situation.


OTOH, most hobby tinkerers are not going to fabricate semiconductor 
devices like MMICs (although I'm sure there's a [semi-fab-nuts] list out 
there for folks who have a 3" wafer line in their garage).
