If you know your size for sure and can do some fine adjusting bikesdirect is a good source for reasonable priced bikes. I bought the Windsor Tourist, now I know its a 27 speed bike and all that but it is very comfortable and will give you a lot of versatility its a touring frame with pretty slack geometry but gets right down the road and I like the fact that its cromoly steel. Its $599.00 USD and free shipping in the USA. I did a few changes after I rode it for a week or so. different pedals and Koolstop brake pads. If you aren't comfortable doing the adjustments your LBS will for a fee of course. Any bike I would buy again from BD I would make sure the wheel bearing don't have too much preload as with the headset, mine came with enough grease but just too tight after I backed them off a bit the thing rolls like like butter. Just another suggestion you may have something completely different in mind but I just don't see the attraction of an IGH.
