i don't know where you bought the machine but you might ask them to 'throw in' that T-bar guide. I bought my machine at the regional distributor and i asked for that and a bunch of bobbins. He threw it in along with 10 bobbins....I use the T-bar guide along with the compensating (quarter inch) foot and the QIAD 'sew straight' and finally get a good quarter inch seams.
