3rd Party Widgets and Oscilloscope

Question

Hi there, I am looking for 3rd Party user controls. What I am interested in is instrumental widgets and in particular a full blown oscilloscope to use in C#. I have found libraries from National Instruments-Measure Studio, 9Rays and IoComp. At the moment the IoComp is looking pretty attractive and seems to have an oscilloscope (Scope Component) which can handle triggering of waveforms (rather than just plotting waveforms on a grid). Has anyone used these libraries and have any comments? Does anyone know of any other libraries which will provide me with an oscilloscope component (not just a plotting component) as well as widgets? Thank you in advanced.
