Hey guys! I'm Kendall with Fluke Networks, for those of you who don't know me. Seems like there's a few questions, so let me see what I can help with
You definitely got the main delineation between LinkRunner AT 1000 & 2000 right - 2000 also offers network testing over fiber. LinkRunner ATs have a lot of functionality over LinkSprinters, but I tend to lean towards grabbing my LinkRunner for unmanaged environments. They allow for faster wire mapping and tracing, and are actually tone generators as well. The main crowd pleaser for LinkSprinter is it's ability to get the switch advertisement info (CDP/LLDP/EDP) and check PoE, test DHCP, Gateway/router, and make sure you can get an internet connection at that drop (all of this is also built into the LinkRunner ATs).
It packs a punch and the starting model is only $199. It was really made to solve 80% of your troubleshooting issues at a better price point for SMBs. Solid addition to a tool kit!
Hope that helps! Let me know if you have any other questions. I'm kinda new here, but I'll be around
