I think this has come sooner than many expected but Motorola announced recently the end of an extensive product line. Now known as legacy products. Sales will be coming to an end for the following products. XPR3300, XPR3500, XPR7350, XPR7550, XPR5350, XPR5550 and the SL7550 repeater
You can expect to see deals to be had as commercial markets remove from service these radios. There’s a newer set of radios and you can learn more on the Motorola website at: http://www.motorolasolutions.com/en_xu/products/mototrbo.html
