I have been looking at buying a 550. They seem to have many of the same featuresof the more expensive cameras. The first batch of 550's camo units did have some problems. I have been waiting to see if HCO will fix the problems. Bee Busy does the new batch of camo units have any problems? How loud is the filter clunk when changing from daytime to nighttime mode? Hope you guy'swill keep us updated on the new 2.0 upgrade.
Thanks
Mike
