Bar magnet pickups

entee

Evening one and all. 
I am looking at having a(nother) electric baritone ukulele made up, and I'm looking around for pickups.  As it will only have 4 strings, a pickup with poles isn't really going to work, so I'll need bar magnets.
I have an existing uke, that uses a Warman Firebird style.  Just wondering if there is anything else someone could recommend?  4 wire would be good too so I can split.  TIA

Electric mandolin pickup? I think the string spacing should be about the same, and if you do a Google search it turns out there are a lot of options! More than I expected.

Half a P-Bass pickup is also sometimes used for mandolins... although they're just a single coil usually. Or use a Mustang Bass pickup with the coils side by side instead of offset like the bass.

And then, whilst TRAWLING the net, I find these ... http://www.almuse.co.uk/ukulele_pickups.html 
Thanks for all the messages; keep them coming if you have other options

I've used a Guitarfetish cool rails pickup for bass and it was great, would work here too.
