Levyo Ajax Gallery supports Firefox 2.0.1 only??

Well … well Levyo Ajax Gallery has support IE 6.x & 7.x, Firefox 2.x,
Netscape 8.x, not only just Microsoft products (IE). Cool.. yup . .. but the price is still rather “hight”.
Hix … guys, do you know another Gallery built on Ajax like them.
I see some but not cool if compare with them. 100% actions of their gallery are built on ajax
