The exo tanks are really quite nice (I have an arboreal setup for my crested gecko) but IMO not worth it for a beardie. Why splurge on a tank your beardie will grow out of in a matter of months . I recommend getting the 40gb aqueon tank from petco, $40 (got mine almost a year ago for my then-future beardie, even though he's out grown it, I couldn't be happier with the purchase) . Put the extra cash aside for the adult enclosure
