mgm has the kelii long neck soprano for 379 but it doesnt have a pickup. i guess you could install one yourself, since you have not reached your price maximum.
There are several makes of Long Neck Concert Uke's, Oscar Schmidt and Ohana make one in the $200 price range, then there are the Hawaiian built models starting at $700 made by Koaloha, Valley Made, Kanile'a, Maui Music... None of these models include pick ups. Hope this helps.
