I, too, love Busardo...I'm an avid follower. His $/ml chart is great...but, as it only has the cost for 30 ml bottles, it's only so useful when looking to buy those sizes (which I haven't yet as I'm still experimenting with flavors). Diggin your ideas though...we think along the same lines. You seem to try a lot of tobac blends (at least in your spreadsheet) which I haven't really found them as tasty...but enjoyed reading your ratings on the others. I haven't tried the vendors on your sheet though...I may have to give them a look.
