not cheap at that point, and I already have that ST board(I live few km
from ST headquarters, BTW)!.
Still licking my wounds from Eclipse-whatever chaintool, ouch, no way I
am going to mess with that again anytime soon.
I am not in the mood to start another endless project, way too many
unfinished stull in my drawers(as many others I guess).
I like the qrp-kit kit, but I will have a good look at eevb for the
"thunderbolt in disguise" and then I will decide.
