I was thinking the same thing about missing out as you....so I took the plunge this weekend and I have a toe!(been lazy too) It really is nice to be able to make something with some interest to it. If you are concerned about sizing there is an article about a toe up sock formula on http://knitty.com/ISSUEsummer06/PATTuniversalsock.html
where you measure everything after
you do a gauge swatch.
Which helps me since I am usually a naughty knitter and never gauge things....Pardon my linking btw Good luck!
