Don't go with wireless since you have DSL and Cable in your area. I would really love to get Verizon FiOS or AT&T U-verse with their really fast speeds but they are not available in my area too. I use DSL from AT&T the Elite plan which is the fastest available with 6 Mgps and I am paying about 17 bucks for it coze they gave me a promotional price when I called to disconnect my landline. They insisted I keep it offering me lower price than the price of the internet service only without a phone line (which they offer too) so I pay in total around 50 bucks with unlimited national calls for my landline phone where you would be paying the same amount (or more) if you get wireless but with 1/6 of the speed I get and with no phone service (you could use it trust me, don't waste your cell phone minutes). Another thing you should consider, with any wireless form of communication to connect to the internet you will get a high ping rate which sucks if you are an online gamer. I like AT&T DSL too coze it gives me a dynamic IP which would change each time you unplug the modem and that allows me to take advantage of some services online that limit your usage based on your IP address. If you have limits on downloads with the wireless that is not a good thing. I could use 5GB in 3 days just downloading torrent files.
I hope that would help you to make an informative decision.
