Hello John,

I can switch to the Propeller for many projects but there are a couple that I can't.  If the SX isn't an option then I will have to look at PIC chips, AVR's, or the TI430 for those.  Price is one concern but in my case it isn't the biggest factor.  I've used the SX processors as intelligent peripherals and for interfacing.  They are fast and inexpensive.  The biggest reason that the SX is better than the Propeller in these projects is the startup time.  The SX processor is ready immediately while the Propeller isn't as it needs to read its program from an external EEPROM.  That takes time and in some projects that is an un-acceptable delay.  The SX is a really flexible chip that has internal flash, plenty of I/O, can be clocked at high speeds (up to 75Mhz without over clocking), and can run at 3.3v or 5v.

I'm still going to use the SX (while available) but will have to weight all the options when I have to switch.

Robert
