Yes mate the Wilma basically recirculates the feed, so its probably the most cost eefective way of feeding the plants :)
Sometimes when the plants are in heavy flower you do find you may need to top up the reservoir during the week, but most of the time its kind of set it and forget it, although haiving the BluLab Guardian in res, means its very easy to monitor.
One of the downsides of the Wilma thou, is that it takes up about 6" of height in your tent as the plants are set on top of the reservoir, so you do loose some headspace :(
Seems to work well for me, I have been using it like this now for a couple of years, and apart from an LED for the summer months I cant see me changing any time soon :)

I've missed that voice  :D 
Loving the mods to the Wilma Sam, I have never looked at one or anything like it. Dragon is using a base of one atm to catch runoff. I'd defo be interested in getting her set up like yours. So the idea of the wills is to use and reuse the nutrient solution? I'm new to coco pretty much so a bit lost looking at it and trying to work it out. I obviously remove my runoff from trays. Dragon is currently using a huge res which is taking up valuable play area in the man cave so I want rid of that res lol.
