no, not really unless we are talking about late 80s and early 90s scopes like 2440... Update rate as important as it is, it is not really a "critical" spec. it is important in catching glitches and ra

prices of used scopes never go up because of "paying attention" to them or praising them on this forum or other forums. the only things that raises their prices are publishing repair or upgrading info

tds5054 for $1000!!!?? who in the world would buy that? That would be a rip off. Even TDS5104 doesn't sell for that kind of cash. This is not TDS7000 series, although even TDS7054 is not worth $1000 t

two things that you'll lose over the chinese scopes that you mentioned are size/weight and record length. These TDS5000 series are pretty bulky and "loud" (like TDS7000 I assume) and the record length

you can just throw in a completely blank chip in there, no problem reading the old chip and writing in the new one doesn't do much and doesn't do any harm either as I have learned...specially now that
