It depends on what you mean by 'get my money's worth out of the machine.'
If you feel like you HAVE to make it pay in $$$ but don't want to quilt for others, then you may never get your 'money's worth' out of the LA.
If:
a) what you really want is the chance to be more creative, artistic, expand your quilting skills,
b) you have the patience to learn what you need to learn to do all that AND
c) you won't beat yourself up over the cost of the machine and supplies until the day you die
then, yes, you will get your moneys worth.
No matter what, though, you know your DH loves you, and that is priceless!
