The two machines you mentioned are great, especially for applique. They may not be a good choice for cutting an entire quilt, however. You can only cut one layer at a time. Make sure you read lots of info about them and watch you tube videos before making a decision.
You can also try ergonomic rotary cutters, such as the Martelli.
I really think QuiltE has a great idea of exchanging cutting services.
you can also buy laser pre cut kits on John Flynn's website:
