plotters

I need advice on what plotter to buy. My budget is between
US$2-3000. Does anyone have a Design-mate by CalComp? Is it
as good as an HP 7575A? It is very very difficult to get
technical information here in Brazil, so I would be immensely
grateful if somebody in this list could help me with this.

PS-I am an architect. I'll be using the plotter for architectural
drawings.
