The greater Cleveland area offers a wide range of houses of worship, catering to every spiritual need. My chosen church: Micro Center.
They have everything. A playground of tech goodies from Legos to kids' electronics kits to game accessories to speakers to laptop luggage--and, yes, computers too, including parts for PC-builders a nice hands-on Apple mini-store. Every weird unusual part or connector I need seems to be there, and the staff is helpful (some are knowledgeable, the rest are willing to put in some research time). They clearly work on commission, but I haven't found them to be pushy, and I always try to make sure whoever helped me gets to put their sticker on what I buy.
Watch for the shelves/bins with yellow tags: closeout or open-box deals!
I was able to get an obscure camera battery, some Mac games, and a cheap iPad case, without running all over town and ending up waiting for Amazon in defeat. The return policy is painless also. And they have some great deals: cheapest prices I've ever seen on current-model Macs, even better (during certain temporary sales) than Amazon. And they keep previous-model Macs in stock to offer even cheaper/lower-end Macs than Apple themselves sells.
Glad to have such a useful resource in the area.
