   I've used the 400-SPR for a few months and it is a useful addition to my toolbox.  Keep in mind that it is a light duty tool, and if used in that manner it performs successfully.  It does what it is designed to do, and does it well.  The grousing on various sites seems to pertain mostly to marketing problems or using the tool beyond it's design limitations. I've also used the plunge router accessory manufactured by Dremel, and I am less impressed with that.  The primary problem with that is that it does not maintain a constant depth of cut when the plunge mechanism is locked.  I am also less than impressed with the router bits that Dremel sells.  I have found that for inlay type work that tungsten burrs that fit other rotary tools (such as the Foredom) do a better job for inlay work.  You might want to ask around the various luthiers web sites for information.  I am also interested in trying the Stewart McDonald base - it appears to be made to a much higher standard than the Dremel router attachment.  Purchasing the Dremel is money well spent.

   agomega,

   I do a little bit of inlay an I prefer a Foredom flex shaft. These are industrial grade units that will last a very long time. Widely used in the jewellery trade. My brother is a luthier and does a fair amount of inlay with a dremel and hates it. He's just to cheap to replace it.

   The major advantage to the Foredom is the variable speed with a foot pedal. When your routing and come up to very delicate areas you can slow the speed and carefully route. The dremel even on it's lowest speed is still to fast and tends to blow out the small pieces. Foredoms also come with different collets to allow a shank up to a 1/4". This means you can also use regular small router bits instead of the Dremel bits and the motor will be able to handle it.

   I made a small wooden base for mine which you can see in Larry Robinson's or Grit Laskins book. You can also buy a fancy metal one from Stewart Macdonald if you like. Hope this helps.
