Quality

I've found that super cheap junk just is often worth the trouble. You end up having to replace it too quickly, or upgrade to the next quality level quickly, or you might just have an unsatisfactory experience.

High end stuff tends to be only slightly better, but cost way more.

In general I recommend getting "decent" quality stuff in between.

Of course there are exceptions but this is somewhat of a personal decision. I buy high end running shoes, and name brand ketkchup. I buy lots from the dollar store, but not food products, or much that I don't consider "single use".

You've really got to decide where you want your money spent.

Yeah, this post is a bit rambly, maybe when my writing gets better, I'll fix it up.
