I own a VCR but I rarely use it. I like to watch a few old VHS tapes I recorded from the telly from time to time. Yes, it's stuff that isn't available on DVD our online. Plus you get old ads and things, it's a nostalgia trip. But there's nothing about the experience that's better than more modern technologies, imo. It's not like vinyl records.
In terms of collecting VHS tapes, I have a few ex-rental tapes that I suppose would be collectable. Rental tapes came in larger boxes than their retail counterparts and often had artwork that was different to the retail versions and the film release so you'd never see it anywhere else. Blockbuster used to sell off its ex-rental tapes sometimes so I would buy films I liked for the artwork. The tapes themselves had usually been played many times and were not in great shape.
