Wait for Seafire. He's the gooo rooo on Blue Dot.
I honestly would be really really careful with BD in a Hornet case. Blue Dot works really well, but FINDING where it works really well is touchy touchy unless you've got a chrono or really good data. BD makes "real" pressures and then makes SNORTING pressures shortly past that point. Don't ask me how I found that out -- I already feel like a moron.
So, unless you've got a chrono and some prior experience with BD, wait for Seafire.
