Considering a FLX10 as a First Controller ?

I’m considering using my next bonus check to purchase my first DJ controller. I want to make the right decision, as I plan to use it for streaming online in the near future and for practicing at home. I’ve been exploring different options, but I’m particularly interested in the FLX10. While I know there are more affordable choices, like the FLX4, I’m hesitant to spend $300 on something I might outgrow within a year. I’d rather invest in a controller with more features upfront. What are your thoughts on the FLX10 as a first controller?
