Are they worth AUD$800? It's what the market will bear. If you after one, they are rare now, but if you are not chances are you can snag them for a song. Are they sonically and play-ably worth AUD$800? You bet. They are great basses, quite underated as they tend to get linked with 80s fashion. If you don;t care about that then sonically they very good, though 80's OB electronics can a bit dated and noisy, particularly if you are talking about the RS924 or MC924. The passive ones are great, and the RB850 came in a variety of electronic packages. I have had the Blazer - precursor to the Roadster/Roadstar, the MC924 and still have the RS924, RB850 low impedance basses. Australia I have found is less prone to fashion of the instrument you play, and also Australia is a seller's market if you don't need the money. Prices for basses on the used market are at the extremes, either they go cheaply or the seller holds on to some ridiculous price and waits for a fool to commit... and they do turn up if you wait long enough.
