Try quilting in sections to get your tops done. I did that on all my large quilts before I got a longarm, and it really works. Marti Michell has a book that explains a number of ways to divide up the bulk of the quilt so it will fit in your machine. Some of the methods even work if you've already pieced your entire top.
Or... pick your prettiest top and send it to a LA quilter. When you get it back you may be so pleased to have it DONE that you will be ready to tackle the other tops.
