Sounds like a great opportunity for referrals, just not for implant placement but for everything else (tumors, joint issues, surgery issues, etc..) You probably could get some great referrals and provide a great added service to your community. We have been looking (as a lab) into buying one as well because there is no Docs in the surrounding area that has one. However, I live in Michigan and Michigan is the worse pain in the ass when it comes to getting the radiological licensing to get one. As for yourself, it really comes down to who you want to align with as it comes to the lab prosthesis. The CS 8100 is nice and most labs are capable of producing models, surgical guides, and custom abutments, even temp abutments and a temp prosthesis for immediate loading could be provided at time of placement, however the price of the digital workflow might surprise you. As for the Planmeca, its nice but set up for more in office with Sirona's Cerec system. I haven't looked at the costs of each system but are they pretty close to one another?
