Hello all.  I don't know whether this post belongs in Gadgets, Home Workshop or Digital Imaging.  Moderators, if you reckon it should be moved, please do so.

I'm looking for an inspection camera.  I expect to look into wall cavities and similar tight spots a fair bit but am unlikely to be looking inside water-filled pipes.

I've looked in the Jaycar catalogue and I've Googled.  There's a great variety out there but I do not recognise any of the brands, even though I have a pretty extensive background in photography and microscopy.

I don't know what specifications would be considered up-to-date (and I know that next year they won't be up-to-date any longer).

I try not to buy junk from the PRC but it's difficult to avoid sometimes. 

Can anyone recommend a good, reasonably robust inspection camera for occasional use, or can anyone say brand X is generally good value, while brand Y is flimsy junk?

Thanks in advance.
