I'm using Market Samurai myself but I don't have enough time to look for interesting niches. I'm looking for someone who can work with Market Samurai and wants to perform this task. The keyword reseach has to be done in a non-english language. I can supply you with related keywords. You just have to look for the interesting ones with certain filters. If you know how to work with MS this will be easy. If you're interested in this please send me a PM with your experience and price to perform this task.
