Many people use the PC 7518 with fantastic results. You should be able to find a plunge base for your existing router(s). I have 3- identical PC 690's and use them table-mounted, fixed base and plunge base. To me, being able to have everything interchangable is a very nice feature. Since you're satisfied with the performance of your existing routers - you can save money - while adding flexibility by simply purchasing the appropriate plunge base. I have 3- shops full of guys manufacturing things and I insist on using the same setups (as described herein) on everything! It saves me a fortune! Not only in money - but in aggravation, not to mention - usually buying multiples of something gets big discounts! My Dad taught me this principal when I was very young, and I am no longer young!
