Some of us may be reluctant to recommend something as critical as a lifejacket - I have no such qualms*. Those jackets are fine - a good price from a decent supplier and manufacturer. Unless you're going offshore sailing on a yacht, don't bother with the harness - although some will say the D-ring on the harness is handy to clip sh1t to - which is a valid point.
DO NOT buy manual units!!! Those are most likely Halkey Roberts type mechanisms (bobbin) not Hammars, and I think they will suit you better in the long run.
* Until recently I thought that Qualms were a tropical fruit similar to mangos...
