Tifosi are fine and I have heard of them and seen them around, you aren't spoilt for choice at that price range but you are also not limited to one make, it sounds like your limiter is the dealer in your area.
Others to look at, Bianchi, Felt, Specialized - to get an idea on whats around have a look at the Evans catalogue or Wiggle and see what choice you have, check out the names and then do a search on the internet for a local dealer in that brand and go and speak to them, don't rush into it, there are deals to be had, and don't be afraid to go for last years model because its last years, you may find you get a better deal as the exchange rate at the time of ordering was better and this years prices have done up.
To be honest around that price range the worst mistake to make is getting the wrong fit bike, don't buy one off his shelf cos he says its a great deal, buy one because you like it and it fits.
And no, you aren't a heretic, everyone starts somewhere, as for being a non triathlete, welcome to the forum 
Remember - fit (right size), looks (does it match my eyes/outfit), sale price (am I getting a good deal), in that order. Well, OK, fit ...... then anything in any order.
