Stop by a local gas station or smoke shop. I got a really nice spoon from my local smoke shop that was only 9 dollars. Much quicker than ordering one and waiting for it to ship.
What Quagsire said, u can normally find some pretty nice pieces for relatively cheap at a local headshop.
..but why not go ahead and drop a little bit extra on some handblown local glass thats gonna last longer and be made of stronger glass? etsy is a good place to get spoons btw. for cheap too.
