The 53oz motors are a big part of your speed problem. And so is the 12V. But, as Eric said somewhere else, the best you'll be able to get with even 100 oz motors is ~12 ipm.
What speed are you trying to attain? You probably want at least 30ipm, I'm guessing. I'd try to sell the Stepperworld board on Ebay, and get the HobbyCNC. Then, try to find a 24V supply on Ebay. If you wait long enough, you should be able to get one for around $10-$20. And you really need bigger motors, preferably at least 200 oz-in. HobbyCNC has these as well.
And if you still can't get enough speed, you need to switch to something like 1/2-10 acme.
Unfortunately, I don't see any cheaper way to go about it. You could try running 24V through the Stepperworld board, but I doubt it will give you much better performance based on what I've read.
