Hi Byrnemj,
Welcome to TOTV!
As others have stated, new homes sell only for the listed price. If you are receptive to buying a resale, I agree with others that there are great deals to be had. As Challenger suggested, figure depreciation on appliances when comparing resale vs new. Also, add the bond on the new and the bond, if any, on the resale to the total price.
Do use an MLS Realtor in addition to a TV sales agent if you look at resales as they don't share listings. Get a written "buyers agent" agreement with the MLS Realtor.
