I bought a beautiful organiser for the tools I use most. It's from Hobbyzone and I bought him at sceneryworkshop. You have to assemble it yourzelf but it fits very well.
Also bought some small drillbits in China. Very cheap but good quality. You can find them at aliexpress.com When I bought them tey were 50% off.
For organizing the drillbits I made an drill-block so I have them all together.
