How to spend 1.8k GBP in Amazon vouchers?

I had a Nikon d300 with 18-200mm vr and an mb-d10 stolen.

I have, however, since replaced all of these with cash, but I now have the good problem of thinking what to spend the voucher on, which was provided through my house insurance.

Equipment which I currently, mainly use is a d7000, 18-200mm vr, 70-200 2.8 vr i, 17-55mm 2.8 and an sb800 flash.

I'm thinking along the lines of another body, say d5100, ( I do generally use 2 bodies ). A powerful telephoto, say Sigma 150-500mm OS. I maybe need another flash, for CLS.

Apart from a broad section of photography, I have recently taken up Astrophotography and Bird Photography.

My deepest sympathy of having to spend 1.8k GBP.

In keeping with your interest in Astrophotography, try this.
