I have Summer Escape pool, either 15 or 16 ft. Bought it at $125 and been using it as SWG pool. This year would be 4 years but most of vertical bars are rusted at the bottom. Searched on ebay sell around $10 - $12/each/used. There are total 15 bars. The cost would be more than the pool itself and the bars not even new. Where can I get them cheaper? Or use it this year and get new pool next year?
