Amy thoughts - since you say you got a screaming good deal on this machine and you have other BLs and love them, there should be your answer...I think the dealer who said not worth it and offered a "trade-up" is just looking to make a sale/commission. I guess my only hesitation might be the company warranty for only a year......may be industry wide, have never had that happen to me, so cannot compare.....
whatever your decision-good luck
