i got mine for around 40euros (i think it was about 50something $ on sale Amazon) black friday deal.TBH I own a 64Gb mSD and I am still good... actually, I have DECIDED that I am and WILL be good until 200GB mSD get in 30€ range (and I hope it happens soon).
good to know it is sufficient so far, how many games do you have on your mSD? cx
