I went the SIM and TRex, I did the SIM for a couple of months and over the course of those months I got the TRex and all the other parts and built it. I was able to hover nose in the first pack. If it’s built right it’s very stable and parts are cheap. You’ll still crash but you'll get to know it very well. I’ve found if I don’t try to get ahead of my self to much I can go long times between them.

Good luck and enjoy it.
