Not sure about voltage of 520+. Another problem is driver support. It
seems to be based on TI ACX100. Experimental drivers at
http://wlan.kewl.org/ for FreeBSD and http://acx100.sf.net/ for Linux.
No HostAP support though, and seems there are some problems (especially
with nearby 'centrino' wireless). They seem to like changing chipset
without making clear on the box. If you have no choice but D-Link, make
very sure you can return it if necessary.

The Dell 1300 card is Broadcom BCM4306-based with no drivers for
open-source OS (see http://tinyurl.com/2lsdg and /. for some
explanation). I think the reason they're readily available on Ebay is
because people have swapped them with a working card.
Atheros cards have a driver for FreeBSD, NetBSD and Linux (the
frequency setup code is closed-source but that's not a problem). See
e.g. http://tinyurl.com/23s4b and http://tinyurl.com/2gkcu for lists of
Atheros cards. They are available in various form-factors (cardbus,
PCI, Mini PCI).
Mini PCI will need U.FL pigtails which may also be hard to come by
unless ordering from someone used to DIY wireless projects (netgate
etc) which would probably save a lot of trouble (US shipping costs are
quite variable, netgate are fairly reasonable, though small orders can
work out expensive due to the carrier's charge for collecting VAT).
PCI cards usually come with a connector and antenna in a retail pack.
Netgear's cards are available in Europe - google.XX/search?q=WG311. The
dual-band cards, e.g. WAG311, are rarer (and more expensive) but are
sometimes available too. Check several suppliers, prices seem to be
quite variable. Looks like they are often Mini PCI cards in an adapter
(e.g. picture on http://www.microtik.com/Documentation/mini_pci.pdf).
