Was in Plainfield earlier today so decided to go a little further East and check out Force Machinery since I got an email from them that they are now partnered with Rockler.
They are still in the process of re-arranging the store so it was a little cluttered but it looks as though they are looking for more dorkers to come and buy there. From what I looked at as far as price they are surprisingly reasonable. You might find a better price online but if you go there to get something you need the prices are not going to chase you away.
If you are in the area of Union NJ and have some time to kill it is worth the drive to check it out especially since there is nothing else in NJ that I know of for dorkers.
If you have never driven on 22 East of route 206 you are in for a treat. I can't even begin to describe the idiocy you can see crammed into a 20 mile stretch of six lane highway with stores every five feet on both sides and in the median! Traffic laws of the US (or any other country) do not exist in the twighlight zone of route 22 and no police can ever be seen there so venture at your own risk...
