I don't have the money for a dedicated macro, but I am interested in trying out extension tubes. I have used the close up filters some and they do alright. Would the tubes work with my D60? There is so much out there that it is hard to figure it out sometimes.
I may also be interested in an old macro lens if it would work on my d60. I wouldn't care so much about not having auto focus as you normally want to use manual.

The most practical tubes for you would be the Kenko tubes. They come in a set of 3 which can be used individually or stacked. Kenko tubes have all the electrical contacts which will allow for metering and AF even though, as you mentioned, AF isn't all that necessary or needed for macro. The shorter the focal length of the lens you use with the tubes, the higher the magnification you can achieve. You will be quite close to your subject, however. If you have a 50mm lens, the tubes would work well with that.
Some of the older manual focus Nikon Micro (macro) lenses are quite good despite their age. The 105mm f/2.8 (or even the f/4) are very good. They only go to 1/2 life size but with a tube(s) you can get much higher magnification than that.

I use Kenko tubes and the middle length, 20mm, can be handheld with a 105, but the 36 really needs a tripod, so combining them would also need a tripod. The 105d macro in my view is slightly better than the latest version, I have access to both, and it may be cheaper. 105mm gives you working space between you and your subject, especially insects and bugs

The Kenko extension tubes should be a good option. Used with your 50mm lens, any of the three extension tubes can be used. More extension provides more magnification. The challenge will be that at times you are very close to your subject. The 50mm focal length will work well for small inanimate subjects.
The extension tubes will also work with your 70-300mm lens. The longer lens will have less incremental magnification from extension. But for close ups of flowers, butterflies, etc. extension will allow you to reduce the minimum focal length and get closer to your subject. This is good for tight close ups - not high magnification work.
When you get ready for a macro lens, look at some of the third party options such as those from Tamron, Sigma and Tokina. Focal lengths of around 90-105mm work well. Image quality is quite good on the macro lenses from all these companies. Nikon makes an 85mm DX macro lens that would also be a good option.
