At the end of the day, it comes down to two key things: (i) personal preference and the type of 'look' you are looking for, and (ii) your budget - set yourself a budget/limit, otherwise beware its a slippery slope
One of the best bits about mods is you get to design and research the look YOU want.... and that includes a bit of
planning (very important), otherwise if you just add and add and add, you could end up with a bit of a mess (and a hole in your wallet)
