Show me where are Roland's analogue TR808,TR909 or TB303 in retail? That's right, there are none.

The patents on all these circuit designs have expired long ago. Behringer is just offering a cheap analogue alternative to unaffordable used gear.

The boutique devices you listed are not analogue so they aren't more authentic to the original than Behringer devices. If anything, it's no less of dubious marketing.
