Cheapest place to get C5 suspension parts?

[Mike Hall]

Im looking around and the GM parts dealers online and wanted to know where the cheapest place is. So far the cheapest I have found the C5 parts I want was about $1200. Ebay is hit or miss on used stuff as no one wants to sell you a package with everything and it would suck to win half of the parts I need and lose the other half. LOL Im looking to get the following parts.

Upper and lower control arms
Knuckles
Hubs

Thanks
Mike
