The SX150 was the replacement for the SX130. It too has been replaced by the new SX160. It has the manual control your course demands.

The somewhat no-name GE (as in General Electric) X500 also has the same level of manual and semi-manual controls as the Canon, plus a longer zoom lens. Cnet says its shooting performance is slow.

I don't think there are any Nikon cameras under $150 with manual control.
