Looking to add some new brushes Need some help

I want to add a few more brushes to my collection. So far I have LC #1 and #6 round and I have a Prisma Brush Medium. I also have #3 round that came with my Diamond FX kit and a #2 flat. I have a #12 LC filbert. And that is it. Would like to add a few more thinking about adding a 3/4 inch flat not sure what brand would like suggestions. And would like to add maybe the Mark Ried signature Chisel and fan brush. They are a little pricy but if worth it don't mind spending it. What else would you recommend for me to try to have a nice variety of brushes to use and work with.

I am constantly reaching for my Loew Cornell 7000 3 and 4, i have several of each for white, black and colors, so my colors stay true, also like the prisma 3/4 flat

thanks just went a little hog wild and bought 15 brushes.

, I dont blame you, I loove more,, brushes or paint
