Hi,
I have a 510v4, and have found it to be very stable. It has been
running my connection 24/7 since about May with no problem whatsoever. The
only problem with it is that the firewall is quite difficult to configure,
as you have to configure it via a telnet interface.

I have never used the 530, so cannot comment on that. You might want to
take a look at the forums on http://www.dslsupport.co.uk/, as they have
forums for both products.
