Ok, don't buy new.
There are no good cymbals new in your price range. TRUST ME!
Look at used and don't be afraid to mix brands and series. If they sound good together, which many of them will, than it doesn't matter what brand or series they are. A few of the best, most versatile series that work pretty well together are Zildjian A and A Custom, Sabian AA, AAX and Vault, Paiste 2002, Giant Beat, Signature and some of the Alphas. There are others but those are all fairly common. Buy with your ears, not with your eyes.
Seriously, buy used. You will save so much money it's crazy. Here is an example:
http://drums-percussion.musiciansfriend.com/product/Zildjian-ZBT-HiHat-Cymbal-Pair?sku=444549
These are Zildjian ZBT Hi-Hats, purely entry level. They sound "ok" but trust me you'll grow to hate them.
http://drums-percussion.musiciansfr...-Series-New-Beat-HiHat-Cymbal-Pair?sku=441801
These are A Series New beats. Strongly considered one of the finest hi-hats in the world, these are industry standard, pro-quality hats that have been used on
THOUSANDS of records.
Now what if I could tell you that you could get those New Beats for
less than the price of the ZBTs? In fact I know that my local store has about 4-5 pairs of those hats in the price range of $50-$60, right now. They are all older pairs from the 80's to 90's, so you know that they are all broken in, which is a big plus.
I know the allure of getting something shiny and new, but, as I demonstrated, it really isn't worth it. This is how I buy all of my stuff and will continue to for as long as I can foresee. Good luck and welcome to the board
