what would you do?

First I would have to try to decide if it was the dealer trying to close a sale and promising a delivery date, knowing he couldnt deliver. Read many times here about the backlog of Manufacturers, and being in the business , it seems they are familiar with their schedules
I dont think the dealer or manufacturer, are going to reimburse you for the "pellet" expense,nor for the used stove,,,(hope you are somewhat happy with the harmon) I feel that was an outragious schedule with all the changes, however im not experienced enough to determine whether it could be at times the norm.
Some decisions you must come to terms with,based on your personality and peace of mind,,,(which could be most difficult facing a possible lay-off) Best of luck to you. Many stoves are worry free for many years and can certainly be researched here on this forum, in case a alternate dealer becomes inevitable! Sorry dude.

Forget the new stove. The dealer should understand. You have to take care of more important things than buying a new stove to make the dealer happy. You have a good stove, if it is big enough, so keep it and burn the pellets you bought to save heating expense. Now is not the time to drop 4-5 thousand on a new stove.

The whole economy sucks. Cheats, crooks, and politicians allied together to screw all of us. In 2 years if we send more than 25% of the house back to Washington, shame on us.

I would just be honest with your dealer and tell him or her what happened. If you have a good dealer you want to keep a working relationship with that dealer. My guess is that they don't want to lose a customer and will understand your situation and go for the sale after your employment situation picks up. The delivery date may be out of their control and what I would consider to be important is did your dealer keep you updated without you having to call 10 times or leaving you guessing?

Forget the stove..if the 1 you have works keep it...think about your family and the bind you will be in if you go ahead with this purchase..$3-4K is just not worth it especially if you are hearing of layoffs..
.gambling man says fold..you got a crappy deal

i had some of the same issues with my harmon boiler. to the point i cancelled the order. harman's delivery over the past year has been terrible, they are quickly making a bad name for themselves. i bet you arent the only one that has cancelled an order from that dealer. i was given the "work is going to be real slow this year". i am pretty sure i will have a job, not sure how much work there is going to be. i aint buying nothing. i wouldnt buy a new stove if the old one is working.

Forget the stove... and, next time, find another dealer who can get you a stove in a reasonable amount of time.

Tell the dealer you've tried to hang in there but the recession is now catching up with you. A descent dealer shouldn't have a problem with that. You can buy many new parts for that Harman before you get close to the cost of a new stove.

You know what you have to do, keep your used Harman, cancel the new one. Tell dealer about impending layoffs at your company, they'll find another buyer, if not now, in the near future. Stay on good terms with him, because that is where you'll need parts from, the closest Harman dealer, that's the rules. Let him know that when you're ready for a new stove, you'll be buying from them. Good luck with your job.

Common sense dictates that you keep the stove you have.
