Nup, we're all poor because we ride bikes!
I don't even want to think about the money that has passed through my hands and into the till at the bike shop.
In order to save money another option is to purchase by mail order. I bought my current frame (Trek5500) from Clarence St but purchased a Record groupset from England at about half of what I would have paid for it here. But you need to know what you want before thinking about that option.
As for origin of maufacture, Trek will put a sticker on the bike telling you where it has been made.
From memory models 2200 and above are made in the US whilst the cheaper frames tend to come from Taiwan.
Lemonds will vary in a similar way with cheaper full aluminium frames comming form Taiwan but more expensive stuff (with the silly looking carbon "spine"😉 will be made in the US.
The reason I bought a 5500 (and why so many others did too) is that it is a proven frame design which has been raced successfully both localy and internationaly and is known for being reliable. The trek frames generally are all quite reliable. If you see the way I punish stuff you'd understand!
My brother has a full aluminium 2300 from the year before they changed to having a carbon stay (equivallent to the current 2200).
This is also a reliable frame and comes with similarly reliable components (because he worked there he was able to get a mix of ultegra and Dura ace components).
Having ridden his bike fore a few months (and raced it too - don't tell him or he'll kill me!), I found it a bit more responsive than my old steel bike but slightly less harsh in ride, the 5500 feels more taught and stiffer again whilst giving a fairly plush ride too. In my opinion the 2300/2200 offers the best compromise between price and performance.
