Aquamist is a paying vendor on this site so I think I am allowed to post this.

I was browsing the group buy forums and I saw the HFS-1 group buy going on. They are selling the kits for $495 - $575 depending on how many people buy it.

It seems that a lot of people want the more advanced HFS-5 which sells for $895.

But I found out that you can buy an upgrade kit (only directly from aquamist) for only $245 which converts an HFS-1 into an HFS-5.

This means you can get an HFS-5 for $740 - $820

And it turns out they are also throwing in a free tank which normally cost about $40.

With the cost of the tank that means you can save $115 - $195!!

I was able to get an HFS-5 at the group buy price but those of you who missed out last time, don't do it again.
