luciferase culture plates

[Steve McKinney]

we are interested in obtaining an alternative source(s) for 96 well 
plates for luciferase assays
the plates need to be low in cross talk of signal between wells (opaques 
sides to the wells ) 
and suitable for culture of cells in the plates for a 
few days 
the supply we have is very expensive $7-9 per plate.
any suggestions or supplier names would be greatly appreciated
thankyou
