I had a Lecroy LC574 at my old job for some years. When I got it, I was looking at both Tek and Lecroy, and had prior experience only with Tek. I was biased towards the Tek, but ended up getting the Lecroy. It was far more responsive than the Tek, especially when using any math functions. I ended up liking it a lot.
However, after a couple years, Channels 3 and 4 would fail on me. Turned out to be bad relays, which were covered under warranty. The second set failed, and they replaced my scope with a new one, I forget which one. It had Windows and crashed frequently, and did not have filters on the trigger. Oh well.
