The number of adjustable fronts is limited to I think one, maybe two, though I don't recall brands. Perrin is the only one I can easily find. And a package deal front and rear of the same brand is usually the best deal.

For the best deals on a specific bar, check for used or new on the standard forums, eBay and froogle. Sometimes a normal google search will find even better prices if you are specific enough.
