I am not sure that it will do multiple exponentials without some user-defined
help, but DeltaGraph Pro could be useful. It does provide an exponential
function "built-in" and has the capacity to accept user defined functions. Of
course cheap is a relative term -- but I have seen ads selling DeltaGraph Pro
as part of a bundle for $99.
I have used DeltaGraph Pro to do some nonlinear curve fitting for
pharmacological data, and have been fairly pleased with the results. It does
allow you to define and save your own functions for later use.
Hope this is of some use to you.
