What is your intent?
Do you want to mount a camera/lens on something and then get out in front of it (in other words, leaving it by itself with no hands on it)? If so, then there's no question whatsoever that a monopod is NOT the proper choice.
A monopod's real claim to fame is holding the weight a heavy camera/lens off your arms so that you can have it in position to shoot for long periods of time. A monopod does add a little stability (mostly in the vertical direction), but is nothing like a good tripod for holding a camera steady.
A cheap tripod is not something that most of us would recommend to anyone using quality SLR equipment. They have been known to tip over, break, etc., and that is not good for the camera equipment. The latches and adjustments on cheap tripods tend to slip.
You'd be much better off spending $250 or more on a good tripod than buying a cheapie. The reason is that you would probably buy five of the cheapies (due to failures or dis-satisfaction) during the expected lifetime of the good one.
