I'm a tight wad too about most things. I don't buy clothes or shoes unless I have to (but I do have a weakness for lounging pants and shirts). I don't need a new car every few years. I very often do impulse not-buying. I put things back that I picked up while shopping before I actually get to the check-out and buy it because I don't NEED it.
You'll have to let us see your machine when you get it made. :-D
And I'm sure that I will be letting y'all know when it gets here.
