Where to get heat exchanger?

[beagledog]

Anyone know a good supply place for a water to air exchanger? The stove dealer didn't have one the size I need and I want to get the biggest I can fit. Better yet, any brands to avoid? Thanks

While I'm at it, what dhw exchanger is the best? I see honeywell side-arms and I see the plate types on ebay. Is there an advantage of one over the other? Thanks again to all who reply
