Hostel Shoppe sells Cateye computers: http://hostelshoppe.com/cgi-bin/sear...ategory=203000
and long wire harnesses for them: http://hostelshoppe.com/cgi-bin/read...sory=983899553

Any decent bike shop should be able to get a long wire harness for you. I dislike putting wireless computers on recumbents- too many things between the transmitter and the head unit.
