I would recommend other vendors that address the real problem of 11n in 2.4GHz using a single channel architecture such as Meru Networks. These architectures also offer actual RF management not just network management in the RF space. Cisco and other competitors solutions are not really addressing the problem in 2.4GHz other than the advantages of MIMO added to the mix. What's the point in deploying 11n if you can't fully use the full bandwidth advantages due to channelization constraints? Do some homework and I think you will be pleased with what the competition has to offer. I have yet to speak to anyone that is fully pleased with their Cisco 802.11 deployments (new or old). Often the ones that think they are satisfied did not do any other research or testing with competitive products. Good effort Cisco, but keep trying, maybe you will get there someday.
