Well Makita makes adapters for the DeWalt routers I use. I do not think it will be long until someone makes them for all the routers.
If the TS 55 works the TS 75 must work also, I will give one a try.
I found the 117" Makita guide Rail for 176.00, but the best overall price I have found so far is 199.99 including shipping, about 85.00 savings over the Festool rail.
