For clarity, this is analog betacam and not digibeta?
It might be possible to get a used analog betacam deck for a few hundred bucks on Ebay. Tv stations probably dumped a lot of working gear as they upgraded to digital formats as Digibeta decks are backwards compatible with the older tapes.
If it’s the smaller betacam tapes that were used for news gathering, a portable deck might do the trick…
