Wireless Suggestions?

I was wondering if anyone has played around with Proxim's tsunami series Outdoor 802.11a equipment or Cisco's Aironet 1200 Series. Do you have any preferences or can you point me toward some sites with some good reviews/info? I know the recommended ranges and proper LOS spotting for the antennas, but we're getting to the point where we need to decide between these 2 lines. **We're not looking at the new 50+mbps ones due to LOS issues.**

So any info, suggestions, experiences good/bad, opinions or webpages with info would be deeply appreciated! Honestly, large scale wireless is NOT a strong suite of mine..
