I'm suspicious of companies who don't reveal the price until you contact them - are they ashamed of it?
I've seen that it is a subscription product (like pretty much every AutoDesk product, too); $2,495 per year or thereabouts.
I've seen some interesting capabilities on some of the AutoDesk products and they have a monthly subscription, but I'd have to build that into every quote I submit.
TurboCAD is the best value, but everything can be improved.
