I guess I had the exact opposite experience with Kitchen's Plus. Their salesman was pushy, wanted to force us to use specific design ideas. We finally figured it out when they wanted us to use tile floors and we wanted hardwoods. Turns out, they do the tile themselves and it's a high-profit item, the wood floors another company does and the don't make as much money. All the options they were pushing us to we didn't want.
They also kept bugging us for a budget and what we wanted to spend. We didn't want to divulge that info.
Finally, they quit returning our calls for further changes in the design, so we went elsewhere.
Ended up with CabinetPak kitchens. Way better design ideas, better prices, super easy to work with. They never once asked us for a budget. They would just list the pros and cons of each option as we asked. They explicitly stated they didn't want to know our budget so their answers wouldn't seem biased. They came to our house several times to help us narrow down and finalize our selections. They were super easy with change orders and did an excellent job.
