I have a D3 Nov batch unit for sale.... (just saying).... but that monster is going to be considerably higher then buying an S9... and the L3 unit that you mentioned is pretty up there in price also.

You may want to go to www.nicehash.com really just for informational purposes.  If you click their new web site link and follow the promts... you can find their drop down box for calculating rates of return...  click on a specific miner type and it will tell you exactly what coin that machine will mine.  May cut down on your research time.  Just my 2 cents...
