yeah I have a copy of Diptrace as well, but it's not really that great, dxf import isn't adequate, it's also difficult to layout pcb, it tdoesn't thave 0402 sized smt components, I use multisim for my circuit simulations, So I was thinking about utiliboard, I see national instruments has purchased multisim now and the costs have increased accordingly, so I was curious what everyone else is using.
