Adapters are also available which will allow one to use a 65mm diameter router in a 69mm diameter mount. Aluminum tubing of a suitable size works well, Imperial is a bit thin, but metric with 2mm wall diameter works well.
- https://shop.carbide3d.com/products/carbide-compact-router --- https://carbide3d.com/blog/2019/the-carbide-compact-router/ --- includes feedback speed control.
- https://shop.carbide3d.com/products/precision-collets --- these have been confirmed as fitting in the Makita and presumably the other clones.
- https://www.mlcswoodworking.com/shopsite_sc/store/html/smarthtml/pages/rocky30_router.html  --- cord shorter than Makita. lacks closed-loop speed control.

The Makita RT0700C/0701C(X) - seems to be similar in kind to the DWP611. Same sort of aluminium housing and speed control, but without the two LEDs underneath. The 0701 is slightly newer and is intended for the North American market. The 0700 is still available as a 220V model for Europe and other localities which use that voltage. Another difference for the two models seems to be the screw layout for the base(s), w/ the newer 0701 having a standard Porter Cable layout.
The Carbide Compact Router is much the same and the specifications of the RT0701 were broken out in: https://community.carbide3d.com/t/carbide-compact-router-max-power-max-torque-and-torque-curve/23458
Variable speed, the actual no load speeds of one unit were measured as:
1: 9470 2: 12280 3: 16870 4: 22175 5: 27035 6: 29800
