Royal Road is fantastic in terms of value for money, tis true. My first "serious" magic investment was Greg Wilson's Double Take DVD with oodles of sleights and tricks taught well by a truely great magician - perhaps not so much material as Royal Road, but I think the examples of performance etc. make up for it.
I was very hesitant to lay out cash to learn more about magic, but it was the start of a great hobby for me which turned into a great job. Of course, if you just want to learn a few tricks to impress your friends and you don't want to be "a magician" then you might as well save your money and take a look at the tutorials on youtube.
Another thought - if you invest some time and money in things like Royal Road, Double Take etc. then you'll start to acquire the skills necessary to make the most of your investment in the Trilogy.
Cheers,
David.
