Collimating

Hello All,

I've been reading through the article here on "passive" collimating and am still confused about a few items in the article...

1. Do you need a sight tube?
2. Is a collimating 'cap' sufficient?
3. If using a laser collimator, do you still need the other gear? ie. cap and sight tube?

I see that Andrews Communications has the following Laser collimator for $59...is it any good?

At this point, I cannot determine whether its a collimation issue causing out of focus images or whether its an atmospheric affect or something temperature related.

Background Info:
I'm asking about collimation because although I got to see what I believe to have been Jupiter and four of its satellites, it was fairly low in the sky (so therefore more atmosphere to see thru) and was coming through all fuzzy.
