I am sorry if you missed my point. I did not mean to imply that you shouldn't open any more threads. But many of your threads, without some background information, appear to be asking the same basic questions over and over. You seem to be concerned about even taking your camera and three lenses, and yet you are asking about Macro lenses or extension tubes and tripods or monopods, and also everything is on a very tight budget. You can't buy a good, lightweight tripod with a decent head for a dirt cheap price let alone on a very short fuse. You might find some good used equipment at a good price, but you lack the time to pursue this course of action. You need to answer some basic questions before investing in good equipment. What style of head do you want (ball head, joystick head, a pan-and-tilt head or a telephoto lens support, like a gimbal head). On a Tripod, do you want carbon fiber or alumnium, flip or twist locks on the legs).
You choice depends to personal preference as well as budget considerations. Do you want to spend a little now on some equipment that you will likely end up throwing away, or waiting until you can afford what really works?
