At the risk of blowing up the ebay prices, there is a seller (ecpar411) that has 10 auctions for soon to be delivered S9's
[snip]

from my research this is a hash board swap situation (just a guess) but alot of ebay people by new swap out the hash boards on there old ones then resell the new "shell" with old hash boards. since they dont accept returns ebay is genealy in my opinion a bad place to buy. after all why would someone buy a SKID of s9's jst to turn around and sell them at half price ?

Speaking of eBay, the sold Avalon6 prices are approaching an average of $300 each!

Due to the age of those miners, recent difficulty increases, new miners coming out, and eBay risks, is it worth it to consider these anymore, or should I just wait until I have enough for a 741?

I would say it depends on how much they cost and your cost and availability of electricity. If you are running them 24 hours a day on electricity purchased from the power company - you will be better off with a 741. If you are running 6 hours a day on surplus or free electricity of some sort, they could be a better choice. You have to do the math based on your individual situation - but for most full time miners you will be better off with the 741.
