How about DIY? I've found recipes for Claussen's/deli-style pickles and they are very easy. I haven't tried though, just haven't gotten around to it. I have tried some quick pickle recipes for sliced cukes and they are pretty good - i imagine a proper pickle marinade of small cukes would work well. If any it'll be far better than the other alternatives

Not a bad idea. Especially since the one thing that separates Claussen's from other pickles is that they're not cooked, so making them should be pretty straightforward.
