There are people who aren't handy and just pay that kind of price.. I kinda feel sorry for them..
Then there are people who just want the job done and the old stuff hauled away and don't care about the price.. I say, do it that way and stimulate the economy..
Then there are those who really can't afford to pay that much and should learn how to do the install themselves. A dishwasher replacement would be the simplest but might require several trips to the HD for the right hook up parts..
The range hood might seem simplest but often requires electrcial wiring (not plug), also may involve a little work adapting the duct.
The range, since it isn't free standing is the most involved and will require the installation of the electric cable or gas line.. Here is where you might want to call in the Pro. A really handy and trusted friend might be able to do it but I don't recommend this for the beginner, because of the dangers..
The hauling is always the problem for those with only a sedan but this is the time you call in favors with your neighbor, friend or relative with a mini van or PU. Maybe you pay someone $50 to do the hauling for you..
If you are considering trying it yourself, I would recommend you first investigate the appliance removal and at this point you will see what electrical or plumbing will be involved.. If you screw up the old, no great loss since the delivery/installer will be hauling it away anyway. Just careful not to damage any water or drain lines that the new appliance will hook up to.
As far as delivery cost go, I would look for a rebate or waver of these.. Dealers are competative and may have some 'wiggle room'. I've never paid a delivery, however, it may have been concealed in the price. I almost always have my own truck and a hand dolly can be rented for a few bucks.
An ad (for free) or phone call will get rid of the old appliance. Most charity/thrief stores will pickup..
