Need advice!

Would like to know have anyone tried using B & W plugin filters for
Photoshop CS or PS Element ?
How are these software type filters compare to the screw in hardware type!
Is there a tremendous drop in quality compare to the screw in lens filter,especially
Polarised filter.
If the quality does not drop much, I find it is worth buying .S$120 for 5
different types of filter in the sofware package. One screw in B & W screw in
filter is equavalent to the price of the filter package.
Please advice.
