Wanna help me buy a really awesome gift? For me?

Okay, so my b-day is coming up and because hubs and I can't ever do anything to suprise one another, I get to pick out my own gift. Yay! He already knows that it is going to be pv related, but I just can't make up my mind what to do. To make it even worse, this gift will include my 4 year work anniversary gift to myself, our wedding anniversary and my b-day, because they all happen this month. So here's the deal. I currently have a 650 eGo-C, two batteries, two cones, a gagillion mouthpieces and atty heads and a couple vision clearomizers. I love my ego into a million tiny pieces. I also have a juice supplier that I love into a million tiny pieces. I'm planning on gifting myself some juice, but I'd also like to add to my hardware. This is where you come in dear friends. Should I get something new to spice things up with? A different company perhaps? Should I get an automatic battery so I don't have to stop knitting? Should I get a bigger battery, or a fancy colorful battery to use with my visions? Should I get some of those rad visions with the LED's in them? Should I take that money and set it on fire and dance around it praying to the pv gods for faster mail service? Any help would be much appreciated!
