I looked for several months before buying my fist pin, I'm very patient and always looking for "the right deal". I have done that with many toys over the years. I bought a RRWoZ last month. I went in just to have a look with my son and we were sold in 20 minutes. Invisaglass is awesome when looking at something that does not have it and the shaker motor really adds to the experience. I paid full pop for mine, expect to take some hit if I decide to sell, but that's not going to happen anytime soon. I do not regret this purchase. If you can do it, by all means do! The machine is awesome and put it in my office as a "work of art" . My office is much more entertaining now....
