--- Quote from: cdev on August 27, 2017, 05:14:15 pm ---The better quality breadboards are modular and can be disassembled into their pieces. --- End quote --- Not all high-quality breadboards are like that. The 3M ones here come in versions with built-in (not snapped on) buses, and I don't think anyone would argue that 3M breadboards are anything but top quality. |

If they don't ship internationally, if someone in US is willing to make some buy for the ones that want and ship it to one address in EU, and from that address in EU the distribution will take place to the group, or other way is get a Shipito address, ship it there and the to EU. They shure look cheap compare to the 3M ones. |

(I just checked mine with a DMM.) See http://www.assemblyspecialist.com/WebStore/TSandDS.html You can see that the full-length ones expressly show that they are 8 half-busses. And that the 3/4 length ones have no such qualifier. --- End quote --- You're right. :-[ I mis-read 3M's Solderless Breadboard and Accessories document on page 5 (P/N's: 923253 & 923749), as I don't have any 3/4 strips to test. :palm: FWIW, mine is an older 3M model (ACE 127 with 3 binding posts instead of 4 & the metal plate is painted blue steel rather than gold anodized aluminum). It uses the gold plated versions of full length distribution strips & circuit strips (Super Strips). |

Gold Aluminum Steel w/ blue crinkle paint finish (same as mine) Keep in mind, both of these models were made decades ago (aluminum first, then steel). |
