I've been very close to quitting a few times now.
I'm lucky that the TRUs, Targets and Wallyworlds I go to are on my errand routes, otherwise I wouldn't even be looking.
We've just been "refreshed" with the Viper/Duke jetpack wave. Hoo-ray
I haven't see any vehicles aside from a beat up Night Specter that I grabbed at a Target 40 miles from where I live. I asked at my local Targets and they told me they never got them (not that I totally believe 'em ).
Plus you've got to fight to find the figs with the corrected molds: fixed crotches, backpack holes etc. And you're left wondering if at some future date Hasbro is gonna released fixed versions of guys like Duke, Flint and Cobra Trooper in their original colors or if you should go through the trouble of fixing them yourself. And like Luftshutze said, its hard enough to find one, let alone enough to experiment with, especially with the semi-destructive disassembly required and the price premium.
Ordering by the case seems to be the only way to ensure that I'll get any figs. I never saw the complete wave 5 at retail. And with Target running $8 for figs, that's fairly competitive now. Of course there are unique dangers on that front as well. I was a little pissed at EE, I was looking to order wave 9, and the assortment with the 2 Snow Serpents and Bats was pre-sold out. So I said "drat" and ordered the Wave 9 v1 assortment with Torpedo and Wild Bill and 1 of each of the rest. I figured I'd been looking for Extra Torps and Bills anyway, and the extreme environment sets (14 figs for $57!) would fill my SS needs leaving me to BAT hunt on my errand runs. Of course right after I get my order shipped confirmation email, EE lists Wave 9 v2 with 2 SS and Bats.
Now we hear that Comic pack Black Destro and clear Wraith are gonna be chases. Hell I'll be lucky to see either regular version at retail. I haven't even seen comic wave 4. And $60 is a lot to drop on a slim possibility of getting one in a case, what with all the other figs coming competing for my dollar. Its taking the fun out of collecting, that's for sure.
I understand that Hasbro has three of the perennial hottest seller lines out there, but the fact that major retailers barely have any joes, even going onto year two of the line is sad.
