Would whole-heartedly recommend Yay.com – it's all fairly straightforward to set up the basics, and if you have any issues (as I have) connecting third-party hardware, they go out of their way to help. Bought a new phone and was having no luck trying to connect it, so I got in touch with Yay – a very patient and chirpy Konnor just spent the whole morning talking me through it, rebooting this and that, and I'm up and running. Couldn't be happier with their service, and I know they're always at the end of the phone (a human being, too – no awful machine filtering) if any problem arises.
