Recommend an access point, 4-p Router wifi

Ok, I have an idea about the best should be this Netgear Wireless MIMO G RANGEMAX Router With 4-Port Switch. I have experienced using this, and it is great. My house is a double story, with a compound-house lot is around 7000sq ft. So, having a RANGEMAX, will result in higher range-which may actually be a bad thing. Another thing I want is a secure AP. I am not so sure how secure is the RANGEMAX with non-MIMO. So recommend me one. Hopefully not SMC and Prolink, the connection is very weak. But if there is no difference between non MIMO and MIMO in terms of security then I actually don't mind. Only that The RANGEMAX has a steep price.
BTW, for now, 1 wireless laptop, 1 wired pc. Wired pc online 24/7. Wireless laptop has a Centrino. Anything that can support BT and azurues is better and gaming.

Thanks.
