You can get an oval hoop frame on a stand for lap quilting - I have the one my grandmother used. It has a cost of about $50 or less.
I'm looking for a link...

scroll down to the F.A. Edwards Hoop with frame for $42.85.
This tilts just fine, is stable, and sits on the floor.
I hand quilt without a frame and do just fine. I use this one less and less...
I also have the Grace EZ3 but haven't even put a quilt on it. I just like to quilt in my lap...
