Jtek's bar end shifter for Alfine 8 hubs is back in production and utahtrikes includes a free jagwire cable adjuster with your order:

Plus they're selling prebuilt Sturmey 3 speed 20" wheels for $49.95 (shifter included):

Flat rate shipping is $9, so the way I see it I bought the jtek shifter and the jagwire and got 20% off on an already cheap replacement wheel.

Sorry for the advertisement, but I was just really happy with the deal I got and the customer service I received.
