This board's reading more like rec.scuba every day. I can't believe y'all are even arguing about this.
To the OP ... any of those packages would make you happy. Get the one that seems like it'll best fit your budget and diving requirements.
The argument about whether a 45# singles wing is too big is just plain silly ... I could see it if he was suggesting a 60# wing, but honestly, I own several singles wings between 30# and 45# and they're all easy and fun to dive. Anybody who thinks an Oxycheq 45 Signature or a Halcyon Evolve 40 is too big of a singles wing obviously has never dived one.
I'm a big fan of DSS gear, and if saving some money and doing business with someone with a proven record of top-notch customer service is important, I'd say give it a serious look. On the other hand, if supporting a local company is more important, then go with the local company. They make good gear too.
Goodness gracious ... why does a simple question about gear have to turn into an argument? It's just gear ...
