With regard to routers I would agree for most work you do not need a. ½′' router, they are heavy and cumbersome.
They come into their own when jointing worktops with a jig, for general projects routers with 8 and 10 mm collets are fine, soft start and variable speed are beneficial.
I have a Makita biscuit jointer, the head /face plate are very adjustable to suit all manner of work .
Think about the projects you wish to do and prioritise the use for the tools you buy.
Check the suitability of the blade for your saw, the general purpose one that comes with the saw is just that, if you are cutting sheet material and more teeth are beneficial, ripping softwood less teeth / bigger gullets are better.
