I already have my boxes (these ones $11 from Amazon) or I'd give the ones from the OP a try. Five bucks is hard to pass up and I feel these minis are a bit fragile for me to want to transport with pegs inserted anyway.

I use a couple Stanley organizers (https://www.amazon.com/gp/product/B00005QWYF/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1), alphabetized. I keep the bases jumbled up in the original box, and only store the bases that I've painted in the toolboxes (painted bases help me track enemies of the same type, so I don't have a need for tons of bases).

Note that there is a large discrepancy in the numbers of enemies by letter (for example, demons, devils, and dragons all start with "D"), so you will probably have to spread letters across compartments, make sub-categories by letter, and/or put more than one letter in a compartment to save space (for example, "x" and "y" can be easily put together).

I only have a couple bestiaries worth of pawns; you might want something different if you have much more than that. Of course, nothing is stopping you from simply getting a lot of toolboxes like this guy did: http://i.imgur.com/13wYjeV.jpg

Pretty sure it's the Stanley 014725 25-Removable Compartment Professional Organizer

I have one of these: Stanley 014725 25-Removable Compartment Professional Organizer https://www.amazon.com/dp/B00005QWYF/ref=cm_sw_r_cp_apa_X1DozbH3WZ1RS

I took a couple trays out to hold pencils and dry erase markers. The little trays are big enough to hold a dice set or a few minis.
