Mr Aqua unfortunately doesn't come with lids. Only brand I have seen that is frameless and comes with lids is YiDing. Apparently they are the manufacturer of the ADA brand tanks, they just aren't labelled as such (quality is identical just no fancy ADA sticker).
Don't know if they are available in America though.
However, you could always just get a lid cut from a glazier and look around for some plastic holders to keep it in place.
I have a Tetra 3G bubbling LED kit. It come with a clear lid, a filter, a pump, and an airstone. I am overall very pleased with it. It is a half-moon style, and the small black rim around the bottom is easily removed, just pops right off, no dismantling or prying!
I got mine for about forty dollars CAD at Wal-mart, but you can probably find one online for less!

Reason: Info Added
Oops, since I can't edit my post, I'd like to add a couple of things to my recommendation- there is a hole in the lid that is for the filter, but I find, since the filter is small and attaches via suction cups, that the small hole for tubing on the led works just as well for the filter tubing, leaving the large hole for a heater, which also leaves room for the LED/airstone tubing should you choose to use it. It also had a feeding hole. I will post pics if you like.
