I have a Shimano Dynamo Hub on my upright bike. It's a DH3D72. I'm very happy with it and if there's any drag, I haven't noticed it. I want to have a similar set up on my recumbent (20/20 inch wheels). Sounds like Son hubs are the best ones to get but I can't afford them. Of all the Shimano Hubs, the only one that appears to be suitable for 20 inch wheels is the DH-3D30. I've read that Nexus hubs (and I'm not sure if the DH-3D30 is a Nexus hub, also referred to as NX-30) give a lot of rolling resistance. I've read on the Optima recumbent bikes site that SRAM i-light D7 dynamo hubs work well with 20 inch wheels. Does anyone have non-SON dynamo hubs on 20 inch wheels? I can't afford the SON hubs.
