Basic Stamp Replacement Question

[Nate Smith]

For those of us who were around back in the PBasic days, or who have worked with the Basic Stamp in non-FIRST related projects, I have a quick question....has anyone been able to find a drop in replacement for the stamp which offers similar functionality at a lower price? Basically, I've developed a small product using the Stamp, and now that we have a working prototype, we're looking for any way to reduce costs. Specifically, I'm using the following features of the stamp:

-Serial I/O
-X-10 Output
-Frequency Output

Any recommendations? I'd even consider maybe splitting the load between two chips(for instance, a separate X-10 control module), if the final cost would be cheaper than the $49 that Digikey wants for each Stamp 2 module...
