The above pictured radios have only been on the market barely a year, & it's rare to see any used ones. The 2500's have been around for many years, & are available on the surplus market from many sources. Alt radios from China included. No comparison. However, the previous Trbo models, XPR4550, & 6550, which are still sold new, are available on the used market for $300, & they are not ALT radios, & come with tags.
