We went with this company
http://www.cncplasmacutterinc.com/
4x4 water table, dedicated plasma head, router,computer,and Delcam software for about 13k. Made our whole robot this year with the router out of 3/16 alu. Needs a good air compressor to operate plasma cutter. Machine accuracy was plenty good for what we needed and price point for a combo machine was the best we could find.
