JMO but I would read the analysts' opinions who follow each before I'd come to either OSIR or MDXG message boards asking for unbiased opinions. Generally, if you contact the analysts, they'll send you their reports. Even the analysts give biased reports depending on the amount of banking their doing or want to do with the companies but at least if their currently doing business, it's disclosed.
I think MDXG has it all over OSIR in terms of products and almost as importantly, management. Google Pete Petit, MDXG's CEO and Chairman.
smelly- you say analysts will send you their reports if you're any Tom #$%$ or Harry with no relationship to the firm??? yeah right.....google Pete Petit?? you mean the part where he's being investigated for insider trading for tipping off a buddy at his prior firm???
