OT: Looking for the Tek 465 of Logic Analysers

I'd suggest to go for the king of the hill at the time, and get an HP 16xx (163x, 165x, 166x, 167x) for all-in-ones or the 16500 if you like to modularize yourself, although tis latter one is much harder to put together since you have to get the frame, the plug ins, the software, etc... 
On the 16yx, the higher the y number, the better the machine (i.e faster, better screens, more memory). They are widely available, starting at below $100 for the earlier machines, and up to $300-$400 for the later ones. I'd recommend to have at least one that has a hard disk, so you don't have to find or make an old LIF floppy to boot from.
As always the rub is the pods/probes. I had to complete my set separately, but they are also widely available.
This is a relatively small amount to pay for what these machines actually are. The later ones have the inverse assembler for the 68000.
I got the luxury one, a 1670G with the pattern generator (which I haven't found an excuse to use yet). Here it is at work:
