Above ground pool heater

We are looking to purchase a pool heater for 24 foot above ground pool. I am looking at a 150K Hayward, 150K Raypac or 125K Pentair. The Raypac dealer tells me they see a lot of Haywards needing repairs in their repair shop. From what I read I like the Pentair but is wind a factor and I also wonder if the 125K will heat the pool slower. From what I read the Raypac might give off more fumes.

Durability with fewer repairs is probably #1 with us. Noise and fumes are probably #2. My husband is attentive to pH and chlorine levels. Any suggestions?
