Dave Spencer,
I don't think anyone is suggesting that your being tight mate by not dechlorinating, or even that you wish to save the money as the cost is so negligable that its not really worth mentioning other than to point out that it shouldn't be a factor when deciding wether to dechlorinate or not. The time it takes to use isn't really a serious argument for or against IMO either (sorry Clive).
Which really only leaves the question of whether chlorine, chloramines and heavy metals are desirable or not and how much damage is done to the filter bacteria colony by ommiting this step and what stress if any is caused to the flora or fauna.
I do think your looking for confirmation that emmiting to dechlorinate is ok but doubt whether you will be happy with any opinion contrary to this until you have lost a tankfull of fish or some geeky boffin type of water quality fanatic can spiel off 500 long and barely deciferable words about the pro's and cons of dechlorinating.
The truth of the matter for me though is that dechlorinating tapwater doen't go even close to the type and quality of water that I want to keep my fish in. So I will make no further comment on this thread as I feel that I have already said to much (I've already given you one really big word that I can't even pronounce(Dichlorobromomethane))and possibly upset one or two people. I also feel that I have already answered your original question to the best of my ability and have nothing further to add. If thats not enough for you then I wish you luck in seeking the answers that you want.
The following link has some real information in it and some links to articles published on the subject and should be good for a read if your that interested.

I have just re-read the above and thought it sounded harsh but believe me when I say it really isn't meant to sound that way. I toyed with the idea of changing it or even toning it down but simply couldn't think of any other way to put it all so decided to leave it as it is please don't take offence Dave we all have our own opinions and methods thats for sure and if we didn't where would we be? Still at square one I guess all as identical clones, now that would not do!!!
