To the OP, I am in the exact same position right now. I have a sirrus and had wanted to convert it over the past year, but I am using my christmas gift coupon to cash in on an 09 Allez for 615 dollars, keo easy pedals, and some cold weather gear. I recommend waiting till you have the money to buy your own bike, I am going to keep the sirrus initially for a back up/commuter bike but may sell it if I would like to spend some money on something else and needed it.
