I have two Vortex 2s and they are both very good rigs. One I bought new and it has proved very durable over the last five years with absolutely no issues. As far as packing is concerned I don't consider it any tighter, either reserve or main, than any other rig. The pop top does have less of a lip than the Javelin, so it does take some care to make it pretty, but both my Vortex reserve pack jobs look prettier than most of the Javelins I see. If I can rig it pretty then anyone can.
The service bulletin was for the Parachute Systems Decelerator reserve, and it was to check the size of the steering line cat's eye and the stiffness of the toggle insert. If you don't have a Decelerator reserve then the SB does not apply.
Overall, in my opinion, it is one of the best gear values around. You may also want to look at a new Vortex. I believe they are having a special now and you can get a new rig for around $1600; you would still need to put a reserve in it though. Here is the contact info: info@parachutesystemsusa.com
