My homemade counter is very good but reads only to 250 Mhz with 4 digits so i need to play with the base time. So i need one counter with 8 or more digits and upper frequency 2.4 or more Ghz and to have good input stage so to read all waveforms. I find Racal at good price but they are 15... 20 years old. From the other way i am not sure for the new and cheap china counters. Who is yoyr opinion????

Usually China instruments are from inside copy of reputable western instruments. Quality depend on price in China too. You cannot expect much from ten dollars instruments, but if you go over say 150 dollars, quality satisfied most of our needs. I have Rigol digital scope and Rigol function and arbitrary waveform generator (include frequency counter too) and I cannot complain over quality and usability, in contrary, both are great instruments. 20 years old instruments mostly needs calibration every 6 months or so, newer one usually have digital auto-calibration solution. 80% of old instruments are heavy used and this way crap or electronically, or mechanically, or both. Take new, if you can, but not really ten dollars item.
