- EU: http://www.dewalt.co.uk/powertools/productdetails/catno/D26200/
It is also available as the DNP611 which is a bare (motor) unit and necessary adjuncts, but no accessories (bases) which allow stand-alone use. Prices on this vary widely, apparently the DNP-series is considered a replacement part and is stocked by stripping compleat sets. Porter-Cable equivalent is Model 450 Type 1.

Collets and Nuts
The standard collet that ships with this router is 1/4" (6.35mm). According to some reports, Dewalt will accept 6mm as well as 1/4" bits. Other collets & nuts (1/4", 1/8", 3/16") are available from several vendors, namely:
- Elaire Corporation (category: Dewalt Style Palm Router Collets) --- please note that the mobile version of their site seems to not list all products, incl. the collets in question. Be certain to match against the part # for the collet for your router so as to ensure compatibility.
- Precise Bits --- ER-style. Ordering 1 nut per collet highly recommended.
- FrezyCNC.eu (currently not listed, but able to order on request)
Stock Speed Control
The DWP611 has built-in soft start and speed control. The speed control commands speeds from 16k rpm to 27k rpm. Users have measured the actual speeds reached at different number settings: http://www.shapeoko.com/forum/viewtopic.php?f=8&t=3918
These are in addition to the versions already listed on the Spindle Options page
