The thing is, that with guitar pedals there are plenty of components that are temperature fragile, such as diodes and transistors. Up until now the ts100 seems the best choice for me. By the little research that I made, it seems to be very accurate as temperature control is concerned and is highly regarded amongst electronic engineers and hobbyists. And last but not least, banggood can ship it to Greece from a UK warehouse so there will be no import taxes, which is a huge plus.
