I found a very nice Islander 36 for sale with a very reasonable price tag. It was well maintained and has all the goodies (rador, water maker, freezer unit, windless...). Here's the catch, it's tiller and I really would like wheel steering with the autopilot and the GPS at the pedestal. How hard is it to convert a tiller to a wheel?! What is the cost? Bottom line, is it worth it?
