There are some very fine older rigs to be had that give great comparison to many of today's newest transceivers but IMHO keeping them on the air might be very challenging when that time does come. Consider both parts availability and one's ability to make needed repairs or to find a good repair shop. A few years back faced with those choices I sold my TS-830S to help buy a TS-590S and have not looked back - both are fine radios no question there just a question of what meets my needs now.
