The one by my house in Seattle was REALLY good. And had a good selection of misc. robotics parts (even if at ridiculous prices). The one by my house in Portland is lighter in some areas but has more Pi/Arduino/etc. variations in stock.

In both stores it was at least three aisles worth of things like components, perf boards, various breakout kits, enclosures, etc.

Fairly good, an aisle worth of general caps and resistors.

The also typically have an okay semiconductor parts selection, but you have to cross-ref with an NTE part number (hopefully they'll have the catalog nearby to look up any specific parts).
