I cannot recommend Psion's online store. I ordered a modem from them, and they charged my credit card but did not ship it until almost a week later. I tried to ask them why, but I only found that their store's "Support" section was just a broken link.
When they ultimately did ship it, they apparently upgraded it to overnight shipping for free. I guess this was to try to make up for the other errors, but I don't know because I couldn't contact them.
