I did a review of it, link in my sig.
I think $40 is a great deal. There have been some issues with people's boosters falling apart, mine included. My dial fell out in the first week I got it. However, service is fast and extremely (extremely) good, which makes up for it, in my book. I had a replacement Booster in my hands 4 days after contacting Artisan and I am in the Philippines!
My replacement booster has been going strong since (knock on wood) and its been to China, Indonesia, Singapore, Malaysia and on 2 domestic beach trips with me in the past 3 months. I have been keeping a velcro cable tie around the dial, as I am a bit paranoid about it falling off, but its been a champ and I am not sure if having the velcro is doing anything besides keeping my paranoia at bay.
