Regarding Bosch power tools. Some confusion my arise, Bosch produce two ranges of tools. Those coloured Blue are the professional range, and designed for heavy industrial use. Those coloured green are intended for the DIY market, and for light use only.
In my opinion, for occasional use, the make doesn't really matter. With professional tools we all have our favorite makes, with some manufactures being better at one type of tool than the others.
The cost should not be the deciding factor. Think of the amount of work intended, and choose what you feel comfortable with.
