Nice sphere, but I think your robbing yourself, you should have it up there for at least 1.58! I would much so like to see a collection!
I use turbo squid to sell my models that don't get used in anything. So far I've been selling for 4 months and made only $72. Some nice pocket money, but unless you have a database of hundreds of high quality models, don't expect to make to much. Oh, and 50% is nothing compared to some other sites that only give 12%. pluse some of those sites try to take the rights to those objects you upload. turbosquid is much prefered
