Any more clues on budget, or a spec?
Bandwidth, sampling rate, number of channels, mixed signal capability? Or just something as similar as possible to the Tektronix scope?
For a $600 or less I went for the Micsig TO1104 in preference to the Rigol, but both scopes go up to 100Mhz, with a 1Gsample convertor split across up to 4 channels, the Micsig is a slightly more expensive but portable with battery.
The next step up is the 2Gsample 2 channel 200MHz scope some of which can be had for ~$1200 or so, the Rigol 2000 series is a good example.
Moving up from there you get the Rigol 4000 scope,R&S HMO 3000 (Hameg scopes etc) if guess around ~$5000,
The highest I was interested in was the R&S RTM2034 or Keysight MSO 3000 series, at around the price level ~$8000 I found the R&S RTM2034 an nicer scope, so bought that in preference.
All prices are year old very crude estimates from memory, and converted from GBP.
For real prices check on line and for the more expensive scopes see what offers the reps have.
Check the 'scopes spreadsheet for other suggestions. A better idea of the requirements or budget might help I have know hobbyist who have scopes that range 1GHz bandwidth Keysight scopes , down to small USB RPi scopes.
