Most of the parts houses I've dealt with are pretty fast. Kits are a little slower sometimes because they have to gather parts from inventory. Bottlehead is an example. I ordered a Seduction phono stage and didn't get it for nine months. Must have had to birth that one. The Paramours I ordered were quicker, two months from order to delivery if I remember correctly. I guess I'm another example - We used to be fast, but have slowed down a smidge. We used to almost always ship same day, but now we're usually taking three days for stuff in stock, ten days for out-of-stock and a month for special orders.
