Any fast screenshot services available?

Question

I need one that does not have a big queue. So, if it does not have it on its cache, it would generate and deliver it reasonably fast (1-4 seconds).

I do have a list of services, what I am asking is if you have experience with any such service that meets the above criteria that you could recommend.

Thank you

Edit: To clarify my intent, I need a thumbnail of any given website approximately 200-300 px wide. I need it fast because it is to be displayed while my the script calculates carious stuff on the background (all this is done and working. I am using a free service for test but it has a huge queue and most of the time the frontend side redirects to the results before the screenshot appears. My code takes about 10 seconds before it redirects to the results usually)

I think that you can do something on your own you by starting an X server and taking screenshots by using "import" command -- I'm pretty sure that it's going to be faster than any external services.
