If you're only playing commercial DVDs (not burning your own), then look for an old first or second generation Toshiba player on eBay. Like most things, the early models were built like tanks back when they cost $500+ for a basic model.
Early players cannot read DVD-R in most cases. You can probably get them for $5 to $10 since they're technically obsolete for most folks. See Link
