I just received my lifereef skimmer but dont have it set up yet. As far as quality and sturdiness i would definitely get another. I'm sure you wont be dissappointed if you get one.
I don't know about the skimmers but I got the LCR2 Calcium Reactor for Xmas and it is great. Excellent craftsmanship, quality and customer service. Jeff is a great guy.
I love my LifeReef skimmer. It pulls out some really nasty stuff. Fairly easy to get dialed in and then works great. jeff at Lifereef has been very helpful as well.
I use a VS3-36" on my 110gal, skimmer is made good for up to 500gal tank, craftsmanship is superb, and it pulls out the dirties smelliest darkest crap you will ever see, great purchase you will not be dissapointed, and whisper quiet to boot, a plus for me, tank is in Living Room cya.
