I'm not going to buy any. They are too small for me -- no room or patience for growing out fish at the moment.
Also, my 7 were all 12" - 24" when I bought them and much less expensive than these 6" ones.
However, if I didn't have any tropicus and was a gar collector then I think the price is okay. People might not see them again for a few years, who knows.
edit; just clarifying I don't think TUIC's prices are at rip-off levels, and definitely not telling anyone to not buy these fish, especially if you've never owned one.
