I have two Raymarine ST2000+ tiller pilots, the first broke one day before the expiration date of the two year warranty. I sent it for repairs and bought a replacement as I did not want to wait 8 weeks for repairs. The replacement bought August 6, 2011 died today. Both warranties run into 2014 so I should have at least one working tiller pilot for the foreseeable future. Performance is fine close hauled up to 15 knots apparent. Doesn't do well on other angles of sail. Becomes totally useless in rough weather. For the time being I have adjusted my expectations to match the capabilities of the ST2000+ but am looking at better options.
