Is there an online store that sells steampunked hardware?

I didn't find anything, but you might want to check this web site. A lot of links and you could contact others who might steer you in the right direction.

there are alot of websites that sell steam punk jewellery and fashion, but actuall working devices is really hard to find. alot are hand made and d.i.y 'ed you can look on threadbangers on youtube and look for the steampunk tutorials and you should come across one in particular that tells you how to make real working steampunk binoculors. if you want steam punk watches, cufflinks, etc.. go to Etsie and click "all products' and then type in steampunk, a whole lotta stuff should come up... mind you, its not cheap.. im still saving up my cash to inhibit the steampunk wardrobe.. (i think inhibit is the wrong word for that sentence, but it sounded good Lol ) Goodluck cap'n -sam :D
