Valeton GP-200
Based on my 10 years experience, I think it is one of the best value for price pedal I tested. It has amazing sound quality. The Amp models are excellent. However some of the modulations are not as good as in the case of a BOSS or Line6 pedals. Also I miss the possibility of using multiple FX effects of the same group at a time. Some manufactures solve this with multiple block, switchable blocks or unlimited combination ( eg. Zoom).
