FWIW I installed a 65 pint whole house dehumidifier for ~1400 sqft in FLA. If I did it again I'd probably do a 90 pint unit.
I installed a standing unit for my crawlspace as it was getting to 70-80% humidity down there. I didn't see the point in spending 5x as much on one of those in-line units, which would be overkill for the crawlspace. Unfortunately, now I'm just having issue after issue. I bought a GE unit that had a pump built in, and it was great... until the pump died after a few months. I ended up replacing it with a separate pump that relies on the garden hose attachment, which seems to work... until the bucket fills up after a few days anyway. It seems like this piece of junk needs to be at this very specific angle, or else water will get into the bucket regardless. It isn't 100% level, but it's very, very close (I took a reading on all four sides).
I'm tempted to just modify the piece of junk to remove the bucket and send the bucket's port into the Little Giant pump that I have. All I have to do is figure out where the sensor is that recognizes that the bucket is installed, and keep it locked down.
Ultimately, I wouldn't have these issues if I would have just gone with a normal in-line unit. I could also do a fancy setup to have it service the house and the crawlspace as my house does sometimes get a bit too humid -- especially if the temperatures are low enough for the AC to not come on, but it's muggy outside.
