There are plenty of options out there. Linksys & Netgeat to name a few. These are cheaper and easier to set up than many others and you gan get them at your local office/electronics store.

I appreciate your feedback but I'm looking for feedback for enterprise level solutions. Perhaps, I should have specified that in the question.

What enterprise level wireless solutions is anybody running these days, other than Cisco.

There are lot of question for that
What is distance b/w two buildings?
How many user in each?
have you cover parking lot and inside the building?

there are some vender :
Linksys, Netgear, Dlink, HP Procurve, Apple,
these venders have various products range in wireless.

those are depend on Distance, inside/ outside, POE etc.
Prefer POE AP

Thanks for the input, I know there are a lot of questions, but again, that's not really what I'm looking for. Apple, Netgear, Linksys, DLink, those aren't going to cut it. I'm looking for what hardware people are using/have the most feedback with in regards to enterprise level solutions.

Cost mainly, but thanks feedback on the hardware. I have looked at Aruba and Cisco. I'll check out Meru.

Thanks
