try rockler.com or see if they have an outlet near where you live. if the outlet dosent have it they will get it. i have had very good experiences with rockler, give them a try
I also have had a difficult time as noted above. I went to Lowes in the next city, explained what i needed that they did not have. Bam!! within the next couple weeks it was there.
But I thank you all for your advice on other places because thats going to help many here.
