Need hardware advice for a Wireless P2P

I am going to be setting up a P2P between two buildings (My church and the pastor's house) which are about 1/10 of a mile from each other. There are some trees and a couple of houses in the way as well so there isn't really a line of site per say. The plan is to mount the Church antenna in the bell tower and have it connected to a weatherized Wifi router or repeater. This will at least put it level if not above the tree line. For the house, I plan to mount a similar setup on the roof or the chimney. Both APs would be connected to their respective networks via cat5. What I need to know is what should i use for AP's (pocket sized ok?) and what should I use for antennas? Also how should I configure the AP's? Router modes, repeaters, bridge?

I am a big fan of OsBridge unit's. The 2.4Ghz units will do just fine... They do work better in line of site but should work fine without at that distance. Tree's are a nightmare and your biggest problem. Try and get as near LoS as possible.

Get 2 x OsBridge 24XLGi (Built in antenna's) point them at each other, assign one as Access Point, one as client, assign same ESSID, add Mac addresses for security and away you go. Each come with POE injectors and a 10m length of outdoor grade Cat5e. Great pieces of kit!

Unfortunately those are out of my price range. I really want to spend as little as possible, and only need a 2 meg link at best. Also, i am in the USA.
