If I run sand-find-scanner it finds my scanner successfully but none of the front-ends can find a scanner, what am I missing?
home$ sane-find-scanner -q found USB scanner (vendor=0x04b8 [EPSON], product=0x012c [EPSON Scanner]) at libusb:007:004 found USB scanner (vendor=0x093a, product=0x2603) at libusb:003:004 home$ home$ scanimage scanimage: no SANE devices found home$
Similarly xsane, xscanimage etc. can't find my scannner(s).

Have you looked to see if either of your scanners are reported as working with the sane project ? AFAIK just because sane-find-scanner lists devices doesn't actually mean they are supported.
Also I presume scanimage -L gives you a similar error about not finding devices.

Yes:-
home$ scanimage -L
No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages).
However I'm even more confused now as I did get it working last night by adding:-
usb 0x04b8 0x012c
to /etc/sane.d/epson. After doing this xsane, scanimage and the Gnome scanner applet all found the scanner, now they're not finding it again.
I seem to remember I had this problem before, the Sane documentation is very little help at all. It seems to assume that once sane-find-scanner has found the scanner everything is OK, there's *very* little help for what you do when you have the scanner recognised as a USB scanner but no software can actually see it.
Aha! Turning the scanner off and then on again gets it recognised. I suspect this is a USB'ism rather than a specific scanner issue now, I never did get on with USB devices!
