scribbles that matter on amazon is only $20! the pages are white and 160gsm. It's the same thickness as archer and olive, but there's free shipping through prime and $10 cheaper! highly recommend, i love mine. if you get it from a different website, make sure you get the pro version, since that's the one with the thick pages

I really like the Scribbles That Matter brand on amazon, the kind without dumb glyphs embossed on the cover. Roughly $20, good paper thickness, nice colors, pen holder.
I tried the Leuchturm once, but found the pages to be too thin, and missed the pen loop.
