I went on line for about 2 hrs. one night and just searched and searched until I found a 15 X 20 with freight free. I think it was from the vets. site Foster & Smith or Best Nest. Can't remember. I looked for freight free as they are very heavy. I moved mine around with my bucket on Kubota and dragging. Spread it out in back yard, checked for holes then rolled it back up exactly as they had it cause then when we put it in I could unroll it much easier. Took 2 of us to unroll it and spread it our smoothly. Fold corners perfectly flat and its much easier with rectangular than round. My old round pond has many fold overs in it which isn't good as it traps crud in there easier. My liner is stapled all around onto 2X4's. One wall is backed with cement blocks cemented tog. as there is a walkway leaning on it. All other walls are framed up 2X4's with 3/4" plywood screwed to it to keep walls from caving as that is a big problem here with the sand. Go back to DG and find my new pond in progress thread and it shows and tells all there. I mean #1 thread. We started end of June and in middle of July fish were put in after letting it settle and run pump etc. for 2 weeks. We learned a little more every time we built a pond. I took all river rock out of old pond and didn't put any in new one as they accumulate too much crud. Doesn't look as pretty but sure is a lot easier to take care of. Takes a 15 X 25 liner to end up with 10 X20 pond. By the time we came up 2 ft. sides and over 2X4 only had 4" sos there was no triming on it and no waste at all.
I think Carolyn's pond is beautiful and I know she enjoys it as I do. Personally I don't like a preformed pond but thats all a matter of preference.
Lots of sies will tell what size liner to get for the size pond you want. Formula for figuring gallonage for rectangle is length, times width times depth and that gives amt. of water. Formulas are also on lots of sites. You can also call many places and ask how deep it should be for your climate so you can have koi and goldfish.
If you have your heart set on one as I said before go for it. You will learn a lot along the way.
