We decided to make our own because of the cost/quality of some we had seen.
A roll of silvered bubblewrap insulation - cut 2 pieces to fit the window - sandwich together with bubble faces inside - stitch binding tape round the edges - fit suckers (available on ebay).
Another benefit is you can make them slightly over size, to get an overlap onto the frame.
