VHS tapes are going for high prices

I picked the wrong side of the Beta-VHS video war. In 1983, I paid about $750 for the first Beta hi-fi VCR. It weighed 32 pounds and basically was an old VCR retrofitted with hi-fi design. In 1986, my house was broken into and the bad guys took the VCR from the third floor to the first floor and left it. Was that because it was too heavy or because it was a Beta? I did eventually buy a VHS VCR.
