The easiest ones I've used that sip blood really fast and take a small amount are Accu Check Aviva and the Contour by Bayer, but the Wal-mart Relion does well too if you need something with cheaper test strips.
Freestyle is also good too, but when first starting out, trying to get the blood on the side of the test strip and on the black spot is not as easy as Accucheck or Contour's test strips, in my opinion.
