Bits n Bobs sources?

Anyone recommend a good source of wee  bits n bobs ( weapons,packs,pouches etc etc) to use when converting figures? I have in mind 28mm scale and Rogue Trader/ Fantasy setting.

Inspiration and a confession

Confession time- I have never played WH40K and have never been particularly attracted to the modern gaming of the 40k universe at all. However having bought the first edition of the rules- Rogue Trader I have become more and more interested in the universe portrayed and the  potentiality for small colourful skirmish games set therein.
You probably know this blog already but I would like to highlight it anyway-

It is filled with inspiring conversions of figures which are really well made and beautifully painted. Even if it's not your scene pop by and wonder at the artistry.
Finally what do I need to read next for background and local colour- are the novels any good?
