Opinions on 0402 design kits

We are considering to purchase 0402 engineering design kits, both capacitors and resistors. Who can give me some recommendations or disapprovals?

For RF capacitors try the ATC 600L series since they have high Q and high WVDC.

For general purpose caps try AVX since they have the SpiCap tool.

These guys make a good resistor kit:
