I've been using PCSX 1.7 for ages now. It's been incredible, they were putting out lots of regular updates for it. It was clearly a ton of work and that work paid off. It's a really great emulator!
The funniest thing is that due to extremely slow stable release schedule, basically no one uses the fixed versions and instead go for the "nightly" releases, so most people already used the version with all of these upgrades.
