when using a polarizer, how do you get the clouds to stand out white, with out a blue haze to them. thanks

1) Make sure the sun is at a 90 degree angle to you and the subject, if possible. Straight on or directly behind you is no good.
2) Rotate the CPL until you get the best balance. A white cloud should, at the very least, stay white.

A polarizer should not give a blue haze to clouds, they are color neutral..
This sounds like you are shooting almost directly into the sun, causing chromatic aberration/color distortion... a polarizer isn't much good in this situation, but your clouds should be OK if you reduce exposure by a stop or so..

I have seen cpl's run from $10 to $225 for a 82mm to fit my sigma lens. What is the best brand to buy? Also, would it be better to get a ND filter? I have a f2.8 24-70 sigma HSM and its sweet. Thanks in advance for your information.

they provide and do different things. It is hard to say. I would be careful about a $10 one , but the other end may be something you don't need either.
It would be best to go to your local camera store and try out a few brands. Make some tests shots then go home and view the images on your computer and make a decision with your equipment. DOn't use the LCD in camera as it can be mis-leading.

An ND filter only reduces light. This can be useful if you want to reduce the shutter speed or if there is too much light out..
The CPL specifically reduces unwanted reflections by realigning the light as it enters the lens. These are useful for removing glare off water, wet surfaces, windows etc.. This is one of the oly functions you cannot get with processing software..
