Pretty much BC BR and anything around that price mark (1100 - 1500) will be the same (and by same i mean same factory different paint). The next step up is, as GTSBoy said, more money - but it doesn't have to be thousands per corner, you could choose the tiny step of: 1600-2500$ for Cusco, Tein, Greddy, JIC, and if you find a good deal/stretch your budget, 3k$ will get you Ohlins. Though some people would argue that Cusco Tein etc are not worth the price...and I have to say I'm only speaking out of research I've done while deciding what to do, and speaking with people who have these coilovers.
You could also consider not using coilovers and going with a spring and damper setup instead. I myself have gone down this path with Bilsteins + King springs, I'm about to get them installed this week - I will rarely, if ever, use my car on the track/drift so coilovers and constant adjustability is not an issue. Set them up once and set them up correctly, leave it.
Oh and - I've talked to a few mechanics and they ALL recommend highly HSD.
