vikana,
There are many providers charging 30 to 50 dollars/mo. for Level II but give it to you free if you pay anually. That is no great hurdle and it is prudent to pay anually in thoes cases. DBC does put a limit on historical intraday but I don't understand your problem with the (at one time)limit of 50 equities. I simply can't effectively track more than 3 or 4 charts during the trading day and my daily Focus Stock list is usually no more than 15 to 20 stocks. If I ever needed to change the stocks I watched, on a daily basis, I reset my data base (via the manager) to contain up to 50 of the stocks I was interested in. To me, an unlimited data base is only useful if you want to do a market scan and e-signal does not provide that function (sorry to say).
As far as qfeed is concerned, they have expanded their server farms and there are some good servers in their arsenal. The problem appears to be with the design of the default server selection algorithm used in QCharts and RavenQuote. If you do a comprehensive job of scanning the discussion boards, you will find a few qfeed users who are unaware of all the severe problems flying around the boards. That is most likely due to fact that they do not use the default server selection feature of their software. No doubt, there is a problem with qfeed but there are work arounds that are effective in allowing traders to do the thing they do best. When things happen that people don't understand, they sometimes panic, rape, pillage, and burn!
