I bought a 765T to get the lane assist and bluetooth. It's really great. The best GPS I've owned, and I've had plenty over the years. Cost about $100 more than I really wanted to spend though.

Just so you know, Garmin in March announced the nuvi 1200 and 1300 series. Similar features as the 7XX series, but 25% thinner, couple hundred (list price) cheaper, and routing for pedestrians. Suppose to be available in Q3.
