PIC 16F88

The 16F88 really is useful but older device - still manufactured by microchip as of Aug 2014.

It is pin compatible with the 16F84 (that is if you don't assign the oscillator pins) e.g. if you use the internal oscillator it frees up the oscillator pins as I/O. It also has most of the same internal hardware modules as the 16F877(A).

It has six major peripherals (see diagram below) useful RAM and program memory (far more than the 16F84) and an internal oscillator that can run from 125kHz to 8MHz (using a postscaler) or 31.25kHz (a separate internal clock).  

These features make it easy to use with high level languages as it has enough RAM to do useful tasks. The31.25KHz clock lets it run at low power if needed.

As with all the mid range PICs it uses ICSP for programming so it can be programmed in circuit without removing it if the circuitry is designed correctly.

The only disadvantage to the chip is with that many peripherals you are unlikely to be able to use them all at the same time as it only has 18 pins. A similar chip is the 16F877(A) and this is a 40 pin chip so for experimentation is a better choice - even so the 16F88 is extremely powerful.
