Yeah if they're out in abundance, there's some more of many that I'd not mind having. Clone Troopers and Pilots come to mind.
Honestly, I find I'm the kind of guy that, if I'm in the store and have $5-$7 on me, I'll pick up a figure... For instance a WM opened right near my girl's place and we're up there allt he time... They're the only Wal-Mart I have seen with the Japanese and Operation Market Garden military figures I collect... They're not REALLY interesting areas for me to buy up figures on though, but I find that when I'm in the store I buy a Japanese Infantry guy, or a OMG Rifleman every time I'm there... They haven't had Star Wars at all there, so I can't buy a Republic Commando, or a Clone of any kind... Can't even buy a Derlin or Bib Fortuna if I had an inclination to do so, but the military figure analogy is the same to me.
So if I walked in and they have a wall of this HOF wave, I'd pick up a Clone Pilot, sure. I loved teh black EU pilot, and the grey one too. I'd buy more troopers... I'd consider picking up Obi for the customizing potential.
Certain things should just be there to buy... Stormtroopers for instance. If the VOTC figure were out there routinely, I guarantee I'd buy one, two, maybe 3 every time I saw them even if they were in massive abundance. I'd surely do big lay-aways of them too just because they were there and I could. The military lines I buy have been doing better about things like that, so thus I buy more that way I think. Their distribution, sadly, surpassed Hasbro this year... That's a day I didn't think I'd ever see given their horrid distribution in the past and Hasbro generally putting stuff out there.
