You're probably best to replace with what's already there- if you currently have rotary steering, replace it with a rotary helm&cable, if you currently have a rack system, replace it with the same. Teleflex is the most common name in steering systems, (and is available at iboats) so why not go with the leader? If you have power assist steering, you can use either Safe-T QC rotary or "the Rack". If you don't have power assist, you should get either a rotary or rack NFB (non feed-back) helm and cable.
