Thanks to Grumpy and Toddalin, my 4560's are finally up and running.
Just goes to show you what a great resource this site is for parts. If you can't find it here, your in trouble!! I got the 2504's from Grumpy and the 2370's from Toddalin. They were both great to deal with - the prices were reasonable, packing was excellent and shipping was fast. What more could you ask for?
Just wanted to share my thoughts!
