According to what I have here (a table of the different AT), the following
should have an SPI:

  Name          available as
- ATtiny26-16   (DIL20/SOIC20)
- ATmega8515-16 (DIL40/TQFP44/PLCC44)
- ATmega8535-16 (DIL40/TQFP44/PLCC44)
- ATmega8-16    (DIL28/TQFP32)
- ATmega16-16   (DIL40/TQFP44)
- ATmega161-8   (DIL40/TQFP44)
- ATmega32-16   (DIL40/TQFP44)
- ATmega64-16   (TQFP64)
- ATmega128-16  (TQFP64)

The ATtiny26 costs less than the 2313 and seems to have allmost everything
the 2313 has, too, except for the 16 bit timer:
