We don't really do price appraisals here. Such talk is really discouraged; checking the marketplace rules section will tell you how to post a wanted ad and what information to include in it.

That being said you're talking about the O2. It's a decent first machine but there is some caveat emptor because the plastics tend to be brittle and you need to make sure that the seller is aware of how to properly pack it.

The octane is the other primary entry-level system I recommend because while it is more expensive and heavier they tend to be incredibly reliable and they have immense upgradability on their side.

Welcome to the forums and please let me know if you have any questions.
