Turn the images into sprites there is a lot more slowing your site down then DNS and it is part of it but most of it is hosting and I did combine your JS files for you your CSS files were already combined.
These are some of the things slowing down your site and causing DNS to have to go back and resolve every time. their at the bottom. You do not have enough requests to have such a slow site let's definitely upgrade your DNS and better hosting it does not have to cost more

here is the speed chart comparing the major DNS companies
http://www.solvedns.com/dns-comparison/
DynECT is my preferred. Dyn.com Keep in mind you can make a deal with NSone.net for everything you need for much less than you would imagine. Speedyrails.com resells edgecast route DNS for the price of $40 you can have 25 million queries per month way more than you need. The company that might fit perfectly is DNSmadeeasy.com they have incredible performance like the others with a base price of $29 a year so when you pay that no more payments for a year. This in addition offers you 10 million queries a month way more than you need.
cloudflare gives you free DNS that's very fast.
Look at the comparison of some of the other DNS companies and you will see that they add significant time onto your sites load time

This is a very slow website because of the hosting platform it's on
Try top recommendation would be
https://www.firehost.com/ if cost is not issue FireHost
if it is an issue which is pretty normal.
Rackspace has created four tears of magento hosting from small to very large

if you are not using a managed hosting platform ( I see who your hosting with it appears that you're not)
you can build your own droplet on digital ocean starting at a very low cost and very high performance

other companies I would strongly recommend looking into.
