but I would steer clear of any addons that claim to be "CFS1/CFS2 compatible".
A valid point and the compatibility between CFS/CFS2 did seem dubious to me as well. Anyway, buying an add-on like these and then upgrading it more or less succesfully with freeware doesn't sound such a smart thing to do; that's why I asked for your comments

Still, some of them seem interesting enough and have also also received good reviews: they can't all be bad or rip-off! But using commonsense is recommended
before purchasing stuff like this, eh?
