If you want something new then I'd recommend hitting up JhanPixel or Colie Glass. I feel like I'm always saying this on the forum but they offer such good value I can't help myself.
Colie Glass really seem to be popular these days with so many people on this forum getting their recyclers. There are lots of examples of the different decorations they've done on them in the
Colie Glass thread, just go back a few pages from the end and you'll see plenty of examples. This seems to be the direction they're going with more and more worked stuff being shown on the
artfire store these days and the facebook page, if you see anything you like in the thread that isn't shown in the artfire store then just send them a message using the contact seller button in the artfire store as they have mentioned before that they are happy to make any of the pieces they've made previously. You'll also notice that they do plenty of stuff without decoration if you prefer the more scientific look. It's worth noting that FC members get a 20% discount off the listed prices on most of the items in the store, however I read in a post that this offer will be withdrawn after 31st October.
JhanPixel (Aeon Glass) also have a massive range of scientific pieces in the
iOffer store, there are also some pieces that are being worked on and haven't been released yet which you may be interested in so be sure to check out the
Aeon Glass thread. JhanPixel offers a 10% discount to FC members on all purchases over $100.
I really don't think you could go wrong getting a piece from either of them. I've got two pieces from Colie Glass which are both excellent quality and the customer service was really good too, Andy went the extra mile to make sure I was happy with my purchase. I know a few people who've gotten pieces from both Colie Glass and JhanPixel and they seemed to have nothing but good things to say about both companies and their products.
