The new MCC line would offer a smaller install and uses the same tones and GUI as the gold elite. If you don't need trunking check out the MCC5500. I think the Gold Elite is still supported by Motorola for parts but no new sales. If you have your heart set on one used set ups sell now and then on public surplus websites, like Public Surplus: Government Surplus Auctions
. We sold our Gold Elite there a few months ago - 4 Ops, server, CEB, 3 channel banks with power supplies and BIMs, and the punch blocks. The widding bid was $350. Be warned this is not an easy set up, and you still need to supply the radios which would typically connect to BIM cards with DC or tone remote.
