Hello all! From the amount of steampunk-ish projects here, hopefully someone will be able to enlighten me a bit. Are there any good spots online for finding bits and pieces such as cogs, keys, watch faces, etc.? Ebay seems to sell packs of a bajillion of one type of thing, but I was wondering if there are any sites which sells packs of a little bit of everything, or let you pick how much you want, while not selling plasticky-, very manafactured-looking products. If anyone knows of any real world shops in Dublin that sell such things, that would be a great help too!

Thanks in advance!
