Blocktrades is my one stop shop for STEEM and SBD, It should be yours as well.
It is fast and efficient and very very reliable, sure the limits are a bit sad but you can also double it again in another transaction.
The customer service of blocktrades is by far one of my favorites besides 
Seriously though their responds is less than hours, compared to the other exchanges were they never even get back to you.
Here is this information straight from the site. "This website enables users to rapidly and safely purchase cryptocurrencies without the hassles typically associated with purchasing through a centralized cryptocurrency exchange. " Which is exactly why I use them for all my exchanges if they support the coin that is.
Purchases can also be made very rapidly (speed is dependent on the underlying confirmation speeds of the currencies being converted between) and large purchases do not tend to move market prices the way they do when placing an order on a centralized exchange. The speed is not so bad it is reasonable at times it is instant!
The Price exchange is well worth it, it is not killer and neither are the miner fees. If you want a fast experiance in buying or selling steem/sbd you better be using blocktrades
Their website is Blocktrades.us
I promise you will use them for all your exchange needs.
