adimatis,
the pa 50 is about 900E or lower if you search around on ebay shops.
Go to www.ebay.de
or www.ebay.co.uk
and do a search for "korg pa". It should come up with items like pa1x, or pa60 or pa50, etc.
Some of them are being sold by "ebay-shops", in germany or elsewhere. They are advertised as new.
Altrnatively search around on the net for germant music shops and you will get thomann.de or lindberg.de or others, with higher prices.
Germany is A LOT closer to Romania, the freight should be a lot less.
