Binding of printouts for the lab

[Harvs]

Where I use to work I had access to one of the standard plastic comb binding machines, which worked alright for binding manuals and other documents.


But since I no longer have access to this sort of thing, and I'm getting a growing collection hard copy service manuals and specific chapters of texts held together by dog clips, I was thinking of investing in a better solution.


Plastic comb binders are by far the cheapest, but I hate that you can't open a manual on itself, so it ends up taking up a heap of room when open.  Also you need too hands to hold it open if you don't have anywhere to put it down.


So I was thinking about getting either a cheap wire comb machine, e.g. (I actually don't know how much these ones are, but ebay has similar items for <$100)

or a plastic coil

So what works best for thick documents in the lab?  Any better options I haven't thought of?

Provided you get sufficient coils so that you can cover the expected thicknesses of manuals the wire is better, though it does rust and stain the paper with time, and both can tear through.
