This is what I call good news : the era of overpriced 33S on eBay is over !
HPcalculators.com (I am not affiliated with them, just a happy, returning customer) is selling this brand new model worldwide at $59.99, via both their website and eBay.
Just for fun : this 33S is scheduled for June at Brussel's FNAC (Belgium) at €149.99, which is equivalent to $177.
Ah, the internet ... :-)
