I've used the $45 (I got it on sale for about $10 off) Obi100 for over a year now. We use cell phones so this is just a backup for home and doesn't get much use, but we've never had a problem with it.
This guy's review gives detailed instructions on multiple setup methods. I have the "multiple Google Voice through SIP incoming" setup. (Using a free SIP account for incoming calls gets around an occasional no-ring issue that I don't know if it's fixed yet, and also is required if you want the phone to have multiple incoming numbers.)
