Cathy,
the Bintel model gives a 2" ep and two 1.25" eps, plus the right angle finder scope PLUS proper collimation knobs on the primary mirror. Along with the moon filter and other bits and pieces that's a great deal at $499
You'll find the finder scope on the skywatcher a real pain in the wotsits to use, as you won't be able to get behind it properly. So that's another $80 value included with the bintel option.
