Not much in the way of this m/b on Ebay but seems to be plenty here with
widely varying prices:

I've never bought from these Chinese sites before, can I have faith in
their assurance that the item is working and their warranty is genuine?
Also would I be liable for import duty or similar?

Ooo, this looks easy. Only 38 steps.

The processor (E-450) could be soldered down,
and not in a ZIF socket. Makes no difference.

Someone wants $15 for it.

I think I'd want to study the problem some more,
before committing to a repair like that. I'd want
to boot an alternate OS (a Linux LiveCD) and see
if it works any better. If that's an eMMC drive in
the socket, I might want to swap in a spare
and retest. Maybe a defect in the eMMC flash is
making it "slow".

To boot a Linux LiveCD, you can transfer it to a
USB flash stick. Hybrid images, all you have to do
is a sector-by-sector transfer. No need for unetbootin.
