What about extension tubes?

[rstorm]

been posting and searching but no luck yet. does anyone know what kind of extension tubes i could get on ebay for nikon lenses? there are some on there for real cheap but wonder if they need to be top brand to be any good? Kenko goes for around $170 but there is another set of 3 for like $20+.

thanks

i got $10 macro tubes and they worked fine. Its not a very complicated part to get wrong.
