QuantHouse is in the same range of price than interactivedata (ex Comstock actually).
The great thing about Comstock is that they cover 180 markets, but for the test we did they are absolutely not low latency. They are often even slower than Reuters. I mean we are speaking here about 200 or 300 ms minimum up to several second late.
We also use them as they cover much more markets than QuantHouse. But we cannot run low latency algo with it. And by the way it is a very difficult API to integrate and the doc is never up to date. Which is often painful as you waste hours debugging just because the doc is wrong.
eSignal is a Comstock product, and then is based on the interactive data feed.
