Should I take the plunge?

This is scary. I'm seriously thinking about spending $1000 - $1500 on a triathlon bike. I have already been thinking about getting a second bicycle. Ever since I found myself grounded because I had to wait for a part to arrive, that has been on my mind. There is a bicycle shop in Cleveland, Bike Authority, which will custom build a triathlon bicycle in that price range to fit me. I can also have them adjust my trusty road bike to fit me, even though it seems to "fit" pretty well already. When I started riding my $75 garage sale special some 4 years ago I never thought I'd be talking like this. Am I hooked, or what! :-)
