I have one of the cheaper $30~ Amazon Refractometer and have had no issues with it. I test my display and the new water to make sure they match beforehand.

This is all good advice.
BRS is your friend right now. You can get man made dry rock, a BRS RODI (and you really should get an RODI, lugging water from the LFS just sucks).
I'm sure they have a refractometer like /u/fp4 linked. I went best rather than better and got one of these: http://www.amazon.com/Milwaukee-MA887-Refractometer-Temperature-Compensation/product-reviews/B007Z4ITWU though you can find it cheaper that was just the first google result. It's a worthwhile upgrade. It's just always right. Always.
And Sump vs HOB is a no brainer, sump. every time.
