Product review (5 stars): combo and love it. Here's why
We bought an LG 2.4 cu/ft. combo and love it.  Here's why:  Its compact and easy to hook up (about 24x24x30 and 155 lbs).  You put the clothes in and walk away and all is done upon return.  For example, we put all my wife's nurse uniforms for the week in and it does a fine job and even keeps them from wrinkling with it's 'cool-down' spin every couple minutes.  Also, it is ventless, uses a condenser instead of wasting heat to the outdoors, has no detectable smell.  We are a couple who believe 'Time is Money' and don't want to spend time moving clothes from one device to another, so this is perfect for us.
