Frugal Usenet is on the same backbone as Usenet.Farm
the unlimited frugal servers are newshosting / omicron backbone. frugals bonus server is what is usenetfarm so both backbones together when you subscribe. shouldnt be any real need for a usenetexpress block account since you would have the usenetfarm backup already but i guess if you find a great sale you could throw it into your newsreader.
