Sorry for digging up an old thread...
I was walking through Sears to get to Radio Shack in my local mall to grab a switch for my Porter Cable 690....and guess what I found for $45?
On the discount /clearance rack theres 2 routers sitting on the top shelf...one plunge with a digital display looked like a Bosch unit....and a 320 fix based unit that you guys are discussing in this thread.
The height adjustment/gear mechanism looked familiar...I thought either Dewalt or Porter Cable.
It had no collet so I grabbed a 1/4" from one of the display units....by luck it fit. Now I go back the next day and ask one of the sales guys if I could get a 1/2" collet and he tells me ..."no problem".... so I grab one off the closest model to this one which I believe had a red top....or something red on it.
The collet looked to be the same design but it didn't fit the shaft....so now I have useless collet so I might just return it even though they let me have it for free.
The diagram on Sear parts doesn't specify if the collet is 1/4" or 1/2".
The label # is not the same as the model # on the website. So if you don't have the label # you can't look up the model on the parts website. Frustrating.
I'll call parts tomorrow but I figured I would ask you guys here since several of you have experience with this router.
