Kelly, honest to God, the extra $150 or whatever it is there for a bike fit would be SO well worth it. It's depressing to get a bike and then find out over the next few months that it's really too big--I've done that. Had a bike with a top tube way too long for me and had to get a different bike. And I got a bike fit before I bought the next one, which I love!
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
