I too purchased and watched some of the Modifides from Tampa. I thought the announcers were lacking and the camera shot sometimes did not show what the announcer was talking about.
I don't really care about any of their broadcasts except for USAC and I hope the announcer they have for the USAC races is comparable to the guy SpeedShift had. But for $150 it worth being able to see the races I can't make in person regardless the announcer.
