Welcome to the Quilting Board!

My Viking Sapphire 830 has those features and I love it. Bought it years ago so used should be alot cheaper than I paid.
Never had any repairs so far.
The pop up foot is great and use it all the time. In fact there is no lever to lift the foot you just push a button if you need to lift it higher than it lifts automatically. It automatically lowers the foot when you start to sew also.
Having the right machine makes all the difference. There are so many new wonderful machines , get the one that you want. Sounds like you have done your homework and are ready to make the leap. If $$$ is not standing in the way GO FOR IT!!
My theory is that I can only be as experienced as my machine enables me to be...so if you have outgrown your current machine, buy something that will allow you to expand your knowledge and experience. Remember to research customer service and support after the purchase as buying a dealer is just as important as buying the right machine for you.
go for it-Husqvarna also has that feature-love it for applique.

Vikings also have the pivot option which is great for doing applique. They just came out with two new Opals that are really nice and worth looking into for anyone wanting a good machine for quilting. I just traded my Ruby in for the Diamond Deluxe because it has so many great features even though I loved my Ruby. Easest machine I ever used; sewing or embroidery.

If you don't buy it you will wish you had it each time you sit down to sew. Do yourself a favor and buy it and have a very happy time using it. I bet you will be very happy you did.
If you can afford it and want it - and especially if your DH is for it - GO FOR IT! and enjoy every minute of owning it!
It sounds as if you are seriously worried about being greedy. Why not give an equal amount of money as the amount you will spend on the new machine to your church above and beyond your regular gifts = or give that amount to a non-profit charity and then get your machine.If this doesn't seem like the answer you are seekiing and if you still worry about the issue of greed, maybe you can donate time to charity causes of your choice. Perhaps it isn't the choice of spending on yourself that is bothering you, but the not giving of yourself in a personal way to others that is seeming selfish. Do some serious soul searching. While we seriously care, we board members can in no way give you answers to a serious question like the one you are asking.
