If you are thinking about buying an NGS platform...
Travis Glenn has released the 2013 tables comparing NGS platforms seven ways from Sunday, so you can make an informed decision.
I found them on a blog I follow: www.molecularecologist.com
Table 1a-c: de novo, resequencing and other applications. NGS Platform grades.
Table 2a: Runtime, reads and yield
Table 2b: Costs/run, Costs/MB, minimum costs
Table 3a: Instrument Costs
Table 3b: Computation Resources
Table 3c: Error Rates
Table 4: Advantages and disadvantages of each instrument
