A short while ago my balance went over the magic $100 for the first time and I was able to request a payout. I put the money towards a lens I have been wanting for some time, a Sigma 10-20mm zoom.
This is the first image from that lens to be accepted on Dreamstime.
Not content with just the one purchase I yesterday ordered a Nikon DX 40mm micro. That arrived this morning - I have not even opened the box yet. I bought that for the macro facility, and also for the lightness and image quality that should come from a prime lens. Hopefully that will provide many more acceptable images.
