Thank you all for your input. I decided not to buy the Kuota based on all the feedback I received. I took your advice and went to a LBS and told them what I was trying to do. There is no way I can afford to purchase a new bike so it seems like Ebay or Craigslist is my best option. When I told them this, they seemed to lose all interest in helping me. That seemed strange because I would still want to take my new bike to them for a fitting, buy products, etc. They would still get my business, it just wouldn't be $2000 on a new bike.
With that being said, and their lack of help, I have turned to an "online bike calculator" to try and get an idea of the correct size for me. I'm 6'1", 34" inseam, and 160 pounds. From what I could find, I would fall between a 59-61cm. Now if all the manufacturers are different in sizing, I'm assuming I would be good on a 60cm and then just have a professional fitting done to dial it in.
I've only been riding about 2 months and I can't afford to make another mistake by purchasing the incorrect size again. All of your feedback and advice is greatly appreciated.
