Basically the same as what i have, except the squirrel-cage fan.
Mine is the HSC-V62, which has a temp controlled fan that will push up to 40 cfm when needed. I personally have mine ducted, and it works fine. all copper, three lug latch, and kinda easy to keep clean (i blow through it with compressed air once in awhile).
Try it, you should be able to return it if it doesn't work for you
