I really cannot see why everybody is on bd's back, OK, it's a Tek, etc, but as he has already stated he does have a reason for his actions and also the TDS210 is perfectly adequate for his stated purpose, audio work, even with its crappy digital display and lack of memory depth. Yes, we all know that analogue scopes have a far better display, I have both a Fluke PM3390B 200MHz combiscope and a Tek TDS210, but the TDS210 gets used most because it is quick to switch on, actually sits on my bench so is right in front of me and takes a very small footprint.
If I had bench space like a lot of you have, then I'd probably use the combiscope more, but space prevents it from being the main go to scope. Yes I'd like a colour display etc. but really cannot justify the cost, so the TDS210 suits me just fine, and I daresay bd can identify with a lot of that as well.
