My suggestion would be to work with your LBS. Is there a reason you don't think they're friendly? I agree that it's a problem with bike shops in general (and I have a long winded theory on why that is that I'll spare you the agony of reading), but it's probably worth developing a relationship with them. Go in, tell them that you're thinking about getting a fixed gear ride, this is your budget, and see what they suggest. Ask about alternatives. While you're at it, if you haven't been, you can probably be fitted too. They'll probably comp you some free service for the first 6 months or so and you'll be on better terms since you just bought a new bike from them. Sure, they don't make a ton on new rides (it's much easier to hide profit in accessories and other aftermarket items), but the gesture on your part is good.

Buy from Harris and you lose out on the good will and free service. At that point, any net retailer is the same as any other, do a little shopping around to see if anyone can give you a better price.
