I've been reading over their materials but haven't tried one yet. These are customized for very heavy duty video work. Has anyone dealt with this company yet/ What are your impressions? http://www.promax.com/s-151-promax-one-models.aspxEdit note: The headline for this post has been changed as I was originally mistaken about their machines being based on Apple Mac Pro and using OS X. A big "Thank You!" to Bryan Glynn for pointing out my mistake.
