Secondary glazing to a back bay window

[Sue]

I have a single glazed bay window in my kitchen. All my other windows (including a separate window in my kitchen)  are double glazed.

I had a quote to fit double glazing to the bay. It was extremely high and I wasn't willing to pay such a lot for a room I don't spend a vast amount of time in.

Has anybody had secondary glazing fitted to a back bay window, and if so was it successful and did it look ok from the inside?

And what sort of price can I expect to pay?
