There are a couple of reasons i don't stock the cheap non-samsung ones is because i *think* they don't contain ID's, plus gamepark supply my SMC's so i like to stick to what they say.
Second I've learnt in the past about getting cheap stuff in stock, all the returns start to come back with faults and trying to get replacements out of the cheap places is always a fiasco.
Yep, Ebay is a good place i'd say, especially during this shortage.
