High speed data acquisition card

Hi I am in need of reading some high speed data and do some manipulation on it, Specifically detect a threshold voltage and then log the next 100 points or so to analyze a peak. at least I need 50 mega samples per second througput rate. I am surprised i cant find anything at a reasonable price, any ideas? How is that a US$200 oscilloscope can read at 100Mhz and there is no DAQs avaiable for that price? Thanks in advance for your comments

If 10 bits are sufficient, the RedPitaya Stemlab 125-10 may be close to your budget.

The 14 bit version is better, but costs much more.

Ciao,
