Pre-orders for the remaining units from the first production run are open again! Price for Solaris remains at $3999.00 or 3590 Euros (includes 19% VAT; adjust VAT per your country) in Euros (plus any shipping costs). They have a handful of units left to sell (10 or so), which will ship by end of June.
You can reserve a unit with a deposit of $1000 (or 800 Euros), but the balance must be paid by June 1. (You can also send it in several smaller ‘installment payments’, if that is more convenient for you.)
