Hey fellow fish-addicts!
Well, due to some fortunate circumstances, I am no longer in need of the sump system I have been using for the past year or so (taken care of very well, of course) and so I thought I would see if any of you might want be interested in it versus going through eBay or something.
Here is what I have:
1 Sump:

Which I believe is just the slightly older version of this one...

....and is probably the version rated for a 55 gallon tank
1 HOB Overflow system:

The 600 gph version
1 Aqualifter vacuum pump (only a couple weeks old) with the prefilter -- which is used to not only keep the overflow going, but a great safety device to ensure that the overflow system starts working again after a power outage....in case you aren't there when it happens (trust me, it came in very handy a couple of times).
I also have a few different pumps that I used to power the sump return flow but none of them are very special (well, the good one I will still be using). If you are interested, let me know what you are planning on using it on and I can let you know if any of the pumps I have would be worthwhile for you. Long story short, the pumps I used to have were good when pumping water through the drilled bottom of my 90 gallon tank, but if that is your case, then you wouldn't need the HOB overflow.
Anyways, I can guarantee that all of the equipment is in perfect working order since it was working this morning. I will also send all of the plumbing that I have been using along with it....which means it is pretty much "plug and play" assuming that you can get it under your tank and the plumbing lengths you need are similar to mine (should be easy to change that though).
Right now, I was thinking about selling the lot for $100 or $120 if you want the pump I mentioned plus half of the shipping costs. I will try to post some current pictures of it tomorrow morning so you can see what it looks like today.
