Thanks guys! That's reassuring to hear that the Pegas is well worth it. I was originally planning on spending a little less but features like the head lift and tilting really sold me on it. I will be getting the stand too.
For blades keeping it simple does sound sensible, and as a benefit I will hopefully learn the feel for the blades quicker if I stick to a type until I run into issues. Most of the practice exercises i'm going to try out first are not super detailed so I guess that is why they are suggesting #3 and #5 to begin with - that or it's targeted at beginners like me that are guaranteed to break blades, haha.
I'm eager to get past these though and move on to more detailed projects though for sure, and prepared to break some blades in the process of getting a feel for them
