K.M.
My husband is an electrician and wires houses for them and some other builders here in Texas.
First texas (Gallery)- Good Quality Builder but watch the extras they are outragious.
Lennar-Excellant Quality Zero custamization. By far the highest quality standards
Plantation (MHI)- good quality builder but wouldnt give them top marks
grand- Don't even think of using this builder looks can be deceving.
Kimball Hill- Good quality but for a specific taste. Meaning all there plans are pretty much the same.
Also were are you guys looking to build? And wanted to tell you you are going to find good and bad on all of these builders. In my opinion word of mouth is the best way to go.
I hope this helps you some.
