Looking at getting a starter pool and do not want to (yet) invest in an above ground pool. I am looking at something 18' by about 4' deep. I hope to get a few years out of it, and will probably take it down every fall and erect again in the Spring. What is my best bet and what do I need to consider when purchasing? Also, I am buying in Canada (Ottawa), can anyone reccomend a good place to look for these types of pools and what price I should be looking at?

Thanks,
