Do you believe HOPE to be terribly expensive? It's $120 for several days, which I really wouldn't consider that expensive, and there are discounts for students and (I think) free for volunteers.
Being in NY makes accommodations expensive, but Hotel Pennsylvania rooms split a few ways aren't that bad.
My take on HOPE vs. CCC is that HOPE is much more explicitly political, especially outside security. 30c3 was pretty much the "CCC NSA event", though, which was unusual. Both are fun, but my favorite conferences are the Dutch HAL/HIP/OHM/etc., and USENIX Security. I have super high hopes for Real World Crypto NYC 13-15 JAN, and excited to speak at ShmooCon 17-19 JAN in DC.
