Been reading/learning for awhile now. I have finally decided on a inground vinyl 18x36 now. I was up in the air between this pool and a fiberglass(viking) for a few months. I have contacted two local pool builders for a bid on a DIY kit. One builder installs Kafko and the other one uses Sentry walls and a liner company out of Mi. I hope to get started sometime in July, but I will see what the wife wants to do. I have to keep her happy!!!!
