The hoop I like is no longer made. However, a similar lap hoop is made by the Grace company:

These types of lap hoops sit on your lap and can be tilted to any convenient angle so both hands can be used while quilting. No juggling skills needed!
A floor hoop might also work for you, although they are more bulky:

Edit: I tried quilting without a hoop, but found that my stitches are a lot more even both top and underneath if I use a hoop. One mistake beginners make with hoops is stretching the sandwich too tightly. When I hoop a project, I allow about a fist's worth of "give" in the quilt sandwich. That is, I allow the middle to be moved up or down about 4" either way. This allows you to manipulate the quilt sandwich onto the needle rather than trying to simply manipulate the needle. Makes hand quilting much easier.
