I use Gliderite ball bearing
I use Gliderite ball bearing slides on all my drawer builds. The price is great and shipping is usually quick. However, the last shipment I just received took 2 weeks to arrive. Please consider NOT using FedEx, and use UPS instead. This delay almost put me in a difficult situation as the timeline on my build got extremely small because of the delivery delay with FedEx. FYI, You guys got the package out very promptly.
