You're not alone any more. As of yesterday I'm on board. Too bad I didn't find this one earlier. I listened to the CC and read this presentation... http://goo.gl/jQmIS and now I have a starter position.
It looks like when NexGen launches at the end of 2013 the number of labs in their TAM will be 5X from what it is today with 3 or 4 additional assays.
Management looks incredibly strong with X-Roche/Ventana execs. You might be right... $30 by 2015.. and that might be conservative.
You should check out another relatively unknown medical device co. with proprietary technology that's on a similar growth curve... Novadaq. NVDQ message board... http://investorshub.advfn.com/Novadaq-NVDQ-24616/
I've been talking to myself over there as well...so I know how you feel - LOL.
I believe NVDQ will be a $30 stock by 2015 as well.
