I'd be interested as well (price doesn't matter too much if this figure never sees general release), unless there is a limit they will let you order.
This is one odd Transformers toy. It is a unique mould, but hasn't been listed anywhere as a general release toy, making it the first limited edition figure that isn't just a recolour or slight retooling. If the Aveo TF isn't that good, it reminds me of the mail-order Omnibots (Camshaft, Overdrive, Downshift) - toys that weren't good enough to sell as general release figures, but a small number were still produced and 'sold' as mail-away figures.
