Good morning,

I was recently introduced to the Executech series (via YouTube), and am hoping to pick up some equipment (probably from eBay) to play with it. I currently have a household 1A2 system which works great, but I thought I might want to play with something a little newer in my home lab. Someday I might get tired of pulling large cables for three lines + intercom. :-)

I'm currently looking at the N1024 or N0820, but I see there is also the Executech 2000 - which seems to have more features. Because I'll probably pair some ports for OHVA or SOHVA (not that I need it, but to learn) I don't think I care for the 0308 as I'd anticipate needing more station ports. Then I see there are 'X' models too, which I haven't found manuals for online.

What I can't really find are the years these units came out, can someone give a high level timeline of the equipment, and if there's a sweet spot in terms of features?

Thanks so much,

Adam
