I can always use fresh rotatory blades and a gift certificate to my favorite quilt store. That way, if I need something during the year, it is fun to go because it is a free shop day. I got the westalee rulers and new foot last year too tartan!
I think it would be fun to get a specialty ruler class paid for at the quilt shop too. There is nothing like learning from a pro to get you started using a foot or ruler.
Oh! I have been thinking of getting one of those light kits that attach to your machine to make winter sewing a little easier.
