How long has ecutek been able to flash EVO 5 and 6?

[MattS00]

As the title says. Also, I don't know much about ecutek. Does anyone have any thoughts on them? It seems many people have gotten flashes through them, but there is a level of to general disdain towards them. bla bla bla. Besides that, are they at least worth looking at? Because, I'm not aware of any other real option for tuning for my eclipse?
