Photo Roller Blinds - anyone used a good company?

[Sandgroper]

I want to put two photo roller blinds in the kids bedrooms. There are quite a few companies that do it. Wondered if anyone has had any experience (good or bad) or can recommend a particular one before I take the plunge?

The windows are large (1800 mm wide and 1200 mm high) and have had a couple of quotes upwards of £200. Just unsure of what the finished product would be like.

Many thanks
