Brad,
Bracheen's right - do it now before you get married. Tonight my wife told me she'd never heard me talk about an Alembic til I bought one, which is true. However, I've always wanted one, particularly after hearing Stanley Clarke and John Entwistle playing them. You could do what I did - just buy it, and explain later. Remember, it's easier to beg forgiveness than ask permission, and possession is 90% of the law!
Dave - yes, 5K for a sewing machine. It's a Husqvarna, and it sews, literally, by itself. My wife can even download a bitmap image, save it to disk, put it in the machine, align fabric in it, and it sews the image into the fabric by itself. She also bought an electronic tablet and new computer for her crafting stuff. The way I saw it, it was worth at least two Alembics to me! BTW, pics to come soon ....
