You're a big lad - get to the LBS and work out what size you will need.
A bike that's too small is difficult to adjust to get an efficient pedalling action. But if you're only going to be tootling around it'll be fine. However if you want to go on serious rides (which it sounds like) - say an hour or more - size does matter.
Avanti is an excellent brand.
PS - as a tip, it's usually very difficult to work out if a bike 'runs well' from photos. It's like a car - bits wear out. But if you are just starting out, it's probably on OK purchase - if you find out cycling is not for you, well, you've only burnt 350 bucks. If you get heavily into cycling, when you upgrade, 350 bucks will be a drop in the bucket.
