[sdiy] Oscilloscope recommendations?

[gnw]

Hi folks,

I'm looking to replace my flaky Sencore "$1 surplus special" scope. 
I've been tempted to go after a few Tek 465's and 476's that I've seen 
on ebay, having read nothing but positive comments about them, but I'm 
nervous about ending up with a basket case that has problems.  I haven't 
seen any of these for sale locally.  I've also been looking at a couple 
of new, but affordable models from Protek and Tenma.  They are lower 
bandwidth models (30 MHz), but probably still sufficient for my needs. 
I also have an opportunity to buy a Leader LBO-516 scope locally, but 
the few comments I've seen on them have been mixed.  My budget is around 
$400 USD.  If anybody has any thoughts or comments on these models, or 
any other suggestions, I'd appreciate the feedback.

Thanks,

George
