There are lots of ARM with embedded FLASH and RAM now, some under USD3.00.

Because you are used to PICs already, you could try a PIC32 device, they
are good also, although they use MIPS architecture. I'm using the
PIC32MX575F256H-80I/PT.
USD8.68 @ units, USD6.82 @ 10 units. 80MIPS, 64K RAM 256K FLASH, 6
USART, 2 SPI and much more. There are smaller devices also.

The greatest advantage for PIC users is that their peripherals are 90%
(or more) compatible with the peripherals on the other PIC families.
