Be careful of cheap thread...it can be brittle and break, especially if it is not 3 ply long staple thread. It can also be lint-y and make the inside of your machine a mess. Remember that adage: You get what you pay for! If you make a beautiful quilt but it pulls apart at the seams later, you'll hate yourself for not buying good thread. Why scrimp on thread when you have already spent a lot on fabric? Another adage: A chain is only as strong as its weakest link (i.e. the thread!).
