I've bought two remotes from BlueDo (MX500 in Dec04 and an MX850 in May05) and have had great experiences. They have replied to every email I've ever written. I had a problem with my MX850 shortly after I bought it and they were stellar there too. They referred me to URC and I had to send the remote in. BlueDo paid for my shipping costs to get the remote to URC!

Unless their customer service has changed drastically in the last few months, I would still support BlueDo.
