While interested, when I look at "do I want another set I don't need, or should I invest the money in upgrading my table?", it doesn't seem right to buy more chips. I have two of those chinese suited tables you can find online (they were relatively cheap at a garage sale), but I need to re-cover the rails. The Stardusts are beautiful, though.
If you want to play with numbers, I have a spreadsheet I use to calculate sets when dreaming about my dream set. Apparently, the site doesn't allow them to be uploaded, though (.xlsx is an invalid file type). If you want a copy, PM me and I'll send it to you via e-mail.
