Once Cowan is listed on the ASX, you could always buy a marketable parcel on the market.
Obviously nobody can tell you what price it will be, but paying $500 in a few weeks when its on the market may be cheaper than buying 28,000 TAW shares at todays prices (less whatever you already hold?).
Of course in the early days of Cowan getting started, I don't expect its market cap to be very great, so I'm sure it'll be a great (interesting?) buy in the early days.
All IMO, DYOR, etc.
