It's not the illusion that gets you that reaction, it's YOU and how you handle the effect.
When Kirkham was still doing shows we did two solid hours of amazing magic featuring the most famous illusions in history... not reproductions, the real props used by Thurston, Dante, Kellar, Blackstone, et all... they all got fantastic reactions but it was the simple Orange Bowl routine that everyone remembered, clamored and talked the most about when the show was over.
It was a valuable lesson for me which is why that same piece stayed in my shows as part of my tribute to my teacher.
What you need to define is exactly what I tell all young people
1.) What Kind of General Effect Works Best For You? A Levitation? Cutting? Vanish? Production? Transposition? Metamorphosis? What's going to fit the idea you have for your act?
2.) What Sort of Effect Best Fits the Style & Theme of Your Show?
3.) Which Version of This Effect is Going to Prove Most Practical to Your Typical Performance Setting?
If you are going to pay thousands and potentially tens of thousands of dollars for something, you'd best be able to know the answers to these few questions or else you are wasting your time and money. Buying a major illusion is more akin to buying a new car, not a new trick at the magic shop. As such, you need to know it's going to fulfill your needs and in contrast, you can fulfill its needs i.e. storage, maintenance, transport cases for protection, logistics report for contracted transport as well as Union House Load In/Load Out fees, etc. (believe it or not, some houses do charge the act for such things based on weight... then you have all the other Union headaches that get in the way). On top of all this you have the assistant to think about; if he/she is going to fit and if they are comfortable doing the bit in as quick a time as is required.
My suggestion is that you visit sites like MagicAuction and Bill Smith's on-line "catalog" as well as Owens Magic Supreme so you can take a look at what's out there and thus, better define your vision before throwing your money away. Grand Illusion is a serious field that epitomizes the BUSINESS side of the Show Biz idea. It's not a game and MUST be taken very seriously from start to finish... trust me, I've made and lost more than a few fortunes working that side of thing for most of my youth (from 1969 into the early 90s) What I'm passing on here, is what I was taught by my mentors; some of the best and biggest names in that world, so please take it to heart, it's not just my experience that's speaking here.
Your Next Step Should Be to look at what you have and where you want to go as a performer. You may want to look at how you can take your SWORD BOX and put a twist to it vs. buying a brand new effect... personally, this has been one of my favorite pieces over the years and I find it sad, that it is so rarely seen in today's world. Such a step means you need to invest more into books that deal with Illusion design and method rather than a new prop. I'd suggest you start with the Paul Osborne collection and likewise try to get a copy of the Byron Wells Illusion Plan books (an industry standard) along with the Rand Woodbury and of course Jim Stinemeyer books... these will allow you to better see what is possible, you'll have the plans for building your own but more importantly, this knowledge will allow you to stir up those creative juices within your mind that will help you better refine your dream and work towards making that your reality vs. just buying another prop that will most likely, fall short of your expectations.
Think about it...
