Has anyone attended the Purdue STEP Program?

I have been accepted to the Purdue Summer step program and I was wondering if it is worth the $$$. I have also applied for other summer programs at washu, but I have to pay for the Purdue program before I find out if I was accepted to Washu’s summer institute. Should I take the safe route and got to the Purdue it play my luck? Also how prestigious is the program? Will it look good on a resume? Thanks for the input!
