I always put a 10K resistor between RESET and Vcc. I also always put a 0.1 uF cap between Vcc and ground, right next to the chip.
Admin, if you're paying more than a few cents for a resistor or cap in that range, you're getting ripped off big time.
For instance, the 10K resistor I use, digikey part #RR08P10.0KDCT-ND
4.675 cents each in quantity 200 (that's $9.35 for 200 of them)
The caps are even cheaper:
the 0.1 uF cap I use: Digikey part #PCC2277CT-ND
2.7 cents each in quantity 100 (that's $2.70 for 100). I buy these ones in 500 rolls, since they're even cheaper - $9.97 for 500.
