Source for small oscillator crystals

I am working on a project using an FT2232C. I am trying to find a
source of small oscillator crystals. The smallest I have found so far
is a Citizen CS20 which is larger than the chip I am trying to use. 
Seems rather silly to build this nice   smd board and then have this
huge crystal nearly dwarfing the rest of my components.

ACT in the UK makes miniature SM crystals in a 5 mm x 7 mm package, if that
helps. I've got some 8 MHz ones but haven't used them.

Here is a brief list...

NDK - http://www.ndk.com/
ILSI - http://www.ilsiamerica.com/
MF - http://www.mfelectronics.com/

If these don't suit your needs, drop me an email to the address below
and I will check my data sheets.  I have seen some as small as 2 x 3 mm
IIRC.  I know you can find them readily at 3 x 5 mm.

After looking at the suggested sites, I did not find anything that was
that much smaller than the CS20. The FT2232C needs a 6Mhz crystal. It
seems that  the crystal sizes are in the 9-12mm range.

I did look into ceramic resonators. The FTDI datasheet does recommend
one from Murata with a .1% tolerance, but does not appear to be
readily available.The datasheet claims that .5% would work to but is
not in USB spec. I much rather stay in spec with a larger component.
than risk problems with a smaller less accurate component.
