Your wife is a lucky lady to have a husband like you!! Whatever machine you get her, you may want to look into a rolling cart for a toolcase instead of buying one from Joann Fabrics. Their carts are not exactly cheap, even if on sale. I found a really neat simple rolling cart (for toolcases) at Harbor Freight and I used the 20% off coupon. It was on sale, too. The side may not zip down as it does for the sewing machine cart, but it will do fine for a lightweight machine.
