yep, Ben Eater /r/beneater only ships BusBoard breadboards with all of his hardware kits, because cheap breadboards from C hina suck!! See article at https://eater.net/breadboards
If the one in cmpen is an 830, then I think your only option is for a larger one is Amazon. If you’re looking for an 830 point one, they sell them at the book store. You can get a 1460 or 1660 on Amazon. These ones are more expensive than a typical one, but they are the highest quality I have come across and are wonderful. Even if you’re looking for an 830, I highly recommend this brand.
I bought one of these recently and don't think I'll go back to anything else: https://www.amazon.com/gp/product/B0040Z4QN8/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
Granted, they are 10x what you paid roughly i guess.
