I totally relate, Clone Commander. I have yet to dish out for a VOTC stormtrooper, myself...
However, by some weird twist of luck our Wal Mart had a few Clonetroopers Evolutions sets- fashionably late, this was last month- on clearance! I have no idea why because I never saw them out anywhere; knowing Wal Mart, they kept them in some stupid place nowhere near the figures and then wondered why they didn't sell good.
But the plus side of this was that I picked up two boxes for $15, and I was pretty happy at that. The Sandtrooper rocks (I apparently got the middle set, with the yellow uniforms and the sprayed-on sand rather than the smeary crud), and sad to admit I never bought a clone before then either!
So my totally amazing army consists of one loose Sandtrooper with the pauldron removed (are the heads supposed to pop off and on that easily on these figures? I did it by hand accidentally the first time, and it stays on pretty well when popped back on), one in abox, and two POTF2 Stormtroopers (one with playwear). Likewise, I have four clones total.
I toyed with the idea of modifying one of the Sandtroopers but that just doesn't seem right. I aim to get at least one VOTC Stormtrooper eventually, and fill the ranks a little more with some more POTFs and maybe commtech ones.
Since that's kinda pathetic, I count my two POTF2 Tie Pilots in with my stormtroopers, so my empire has 6 troops! Yay! And the Grand Army of the Republic is an army of 4.
Then again, the Empire looks a whole lot more impressive when it's got 2 and a half ("quick change!' y'know) Vaders in it, no?
Of course, I don't own a single snowtrooper or scout trooper

I
need to get a VTSC Scout Trooper in stores if at all possible, as I really love those guys; they're really my favorite kind of stormtrooper, actually.
