Honestly, there don't seem to be many 6xx series Daytonas around at all.... maybe it is because I am new to the bike world and finding a great example of any bike it tough....
I have been scanning for about 2-3 months (maybe the winter isn't the ideal time to "shop...") and only come across a couple. I have no objections to a 650 or 675 but have a pretty firm budget.
Based on some of the threads here I am budgeting $1200-ish for lessons (I do want some mechanics starter classes to for bikes)... and then obviously significantly more for gear... I won't pull the trigger on a bike until I have a license though because as much as I LOVE the romantic idea of owning and riding a bike maybe I won't feel so thrilled about it after going through the process of learning the right way.

I am very confident I will love it but want to do it the right way.
