Kitchen in slide... steer clear or no big deal??

Thread title is kind of self explanatory, but what are your experiences? There are horror stories, to be sure... just like with almost any element of RVs, but I'm wondering how big a deal this really is? So far, I've pretty much eliminated models with kitchen in the slide from my consideration. Wonder if that's just silly...

Now, if it's not a big deal, but something I should watch, what kind of things do you watch out for? If it's a matter of replacing a hose and or some drain piping with something of better quality/flexibilty right off the bat, I'm handy enough to do something like that.

So, what are your experiences, conventional widsom, horror stories (personal or second-hand), tips, tricks, etc?

Thanks,Dean
