The real workhorse and money maker at our company is Bentley PowerSurvey. It is (or was) less than $2000 and does 90% of full blown design packages like Microstation/InRoads or (God forbid) AutoCAD/Civil3D. The older versions you load to run in either Geopak or InRoads mode. The current version integrates both. Our surveyors use it for mapping, civil engineers for road design and structural engineers for drafting. With the cheap buyin price and cheap annaul subscrption rate it is our money making software. We have one AutoCAD seat, two Microstation/InRoads seats and all the rest of our CAD seats are PowerSurvey. For AutoCAD people think of it as AutoCAD LT done right.
