Oral chelation products?

Which are the best oral chelation products? I've taken straight EDTA but had better results with the ExtremeHealthUSA chelation and suppliment product. Only problem is, at $60+ for one or two weeks (I forget), it's quite expensive. But in addition to the EDTA it has a number of other herbal and supplimental chelation agents - and I can feel the difference.

Question is, are there other products as good or better that you can take regularly that don't amount to a car payment every month?
