I have had the pleasure of using Opusphp "Panda" for over 5 months now and couldn't be happier. Everything runs so smoothly and with amazing speeds for a site with over 10,000 members. I tried a couple of other scripts before I found this one and even
Princess Manda: though each one had some things I liked, they all seems to run slowly and cost a ton of money just to get bugs and problems fixed that came along with the applications. I also paid for the professional installation since I wanted it done right from the beginning and it's been a smooth ride since.
