Sam,
 

I think the SX might still be a good choice for you.  My guess is that the SX chip will be available for a couple of more years based on the quantity Parallax has in stock.  Of course, some manufacturers may try to buy up as many chips as they can, but that shouldn't have much effect on the 28-pin DIP version.  For less than the price of two Basic Stamp 2 modules you can purchase the SX Tech Tool Kit.  The SX/B language is very similar to PBASIC, and it should help you get up to speed very quickly on the SX.

 

If you find that the SX fits your needs you should be able to buy a sufficient number to support you hobby needs for many years.  You can currently buy 25 chips for about $100.  That quantity would more than satisfy my needs for the next decade.

 

A PBASIC compiler would be nice for the prop processor.  One approach would be to write a pre-processor that converts PBASIC into the spin language.  This way you could write code in PBASIC, convert it to spin and then compile it with the prop development software.  A simple pre-processor is not that hard to write.  However, by the time you would finish writing the pre-processor you would probably be an expert on the spin language.  Maybe someone who is an expert in both PBASIC and spin would be willing to write a pre-processor for the rest of us.
