If it costs $350 then there is a high probability it will perform poorly, while the price of a lens isn't really an indicator of optical quality - it can give you a few ideas of how many corners were cut to produce it.
Taking a look at the construction quality of the new DA zoom lens I doubt they made many compromises in its optical design - it will most likely have aspherics to keep field curvature, coma and astigmatism under control as well as ED glass will help control aberrations throughout the zoom range.
