Interesting: Contrasting two cigars side by side

Saw this blog post: http://www.stogieguys.com/2011/09/09...s-at-once.html, in which the author suggests that you smoke two similar cigars side by side to really reach into the difference in profiles and improve your palate.

I think that's a great idea for a newbie like myself. My question is: Do you have any recommendation for a paring that may be interesting, and more importantly, inexpensive? I don't want to waste a smoke since I probably won't be relaxing and enjoying them, as much as analyzing them.
