I saved a ton and have an excellent solution for my 40x20 pool that I installed myself in about one day. This is a Water Warden mesh cover - the model is SCMG2040 and is actually 22x42 so there's some overlap of the pool edge. Heavy nylon strapping on both the top and bottom. Bought it at Home Depot's web site for $593. There are several online sources that carry this so shop around. Came with all the hardware, instructions, etc. Bought a very inexpensive-but-adequate hammer-drill from Harbor Freight for $35. The leaves just blow off the cover by themselves, and I'm very happy with these results.
