I think checked and usable are better. so i would prefer website freerobot2010. may be it 'll be interesting someone else. there are a lot of useful things on this site. i advise nto surf it, i hope you won't regret.
yeah i also use this robot but as far as i know many traders have difficulties with it cause dont know how to install. I found a video where it is told in details how to do hope it will help you too. its really easy to understand you can look it here http://clicks.aweber.com/y/ct/?l=NDy8Z&
