I was looking at some PC based 'scopes.  I have this huge Sencore SC61 unit that weighs at least 25 - 30 pounds, 60 MHZ usable to 100 MHZ.  I'd like to sell it because I don't think I need to go that high doing tube radio repair/ restoration, and frankly, I don't have the room to use it.  Would 20 MHZ be adequate?  Hantek makes a PC based 20 MHZ unit for $69 and a 50 MHZ unit for $149.  Any thoughts?  Thanks!  Joe

I briefly used the 20 MHz version with signals in the 1-2 MHz range. The display looked kind of rough and coarse. So if it was me, I'd spend the extra on the 50 MHz unit. Other than that it worked well, and I think they are adequate for occasional use.
