Anyone own one of these units that's on wheels and has an exhaust like a laundry dryer? I've been considering getting one but there's not much out there in the way of advice or recommendations. I've located three stores that carry them, each with different brands. Costco: Sharp, most expensive of the lot at over 500.00 Sears: Royal Sovereign Home Depot: Everstar, last year it carried a Maytag that had a favorable review on epinions. Epinions also shows a majority of reviews saying the Windchaser models as average to poor. The higher rated ones are the Sunpentowns, but I've not been able to locate one locally. One of the reviewers said he/she bought one from Fry's, which would require me to take a short trip.
