OK all well and good that we're actually discussing the issue rather than just huffing and puffing about how terrible it all is.
A few more points. It was said (to paraphrase) "you read the reviews and then make your mind up. Unfortunately that doesn't always work 9in fact i'd say it works fairly uncommonly), reason being that a fair proportion of reviews written on here are written by people trying to up their post count and / or get into the restricted area. Maybe I'm just being cynical but i've bought a fair old number of things that have had rave reviews and should suit my style but have been frankly appalling. You could counter this by saying i should write a negative review myself, and indeed I have. Considering the amount of material reviewed, however, I think it is fair to say that there is a fair amount of dross out there.
Secondly, I really do fail to see past this individualistic attitude that it is "unethical" to share. Who says so exactly? Magicians create effects primarily because of a love of the art rather than to make a profit. If an effect is marvellous then the satisfaction of seeing that being performed should be enough. And if it is unetical for magicians to share effects, why is it ethical for a magician to run a magic course and charge for it?
It's not worth me saying anything about the owners rights etc, because if you haven't figured this out by now, I would be wasting my time.
And it is this type of patronising attitude which sums up my points.
All originators should be credited. The "intellectual property" argument is taken too far, however. There are very few "new" effects in reality, most "new" effects being new takes or updating of techniques which are rooted in the past.
I don't particularly expect anyone to agree with me on this as it is all down to either having a vested interest or wanting to ingratiate oneself with those who DO have a vested interest. However the knee jerk sanctimony coming from some becomes wearing.
