Hi, I am looking for a MINT condition Orion bass, 4 string only. I consider also Elan or Europa models as well.

This looks a nice one, though it's in the USA so shipping and duty may be something to think about.

Hi, I am considering it, but they want over 300 USD to ship it overseas...

It will cost them a lot more than $300 to ship the bass to Italy if they want it insured.  
USPS only costs $100, but insurance is limited to $650.  
FedEx and UPS are closer to $500.

However... they seem not to be really interested in selling it, as they do not answer to my mails.
This would be my dream bass: http://www.thelowend.net/gallery/viewtopic.php?t=5073&sid=0b4e0a04cc8296771d14be35a847d387

marcinkus, you have great taste, that bass is gorgeous.  
All the best in finding your dream bass.

Thank you ;-)

The Low End bass looks like Adam's (2400wattman) old Orion. One of the nicest Orion's I have seen.

The bass above at the Low End Bass Shop is in the Alembic gallery (previously sold by The Low End).  Available basses for sale are listed in used basses section.

I have an Orion 4 in excellent condition I'd sell for $1,900 shipped.
