Lee, is it Mesu or something else?
I think initially, when entering this hobby, $50 spent on an eyepiece or a filter was a humengous amount of cash. But as we gain experience we also increase in an ability to differentiate mediocre from good. I was infinitely thrilled with "perfectly round stars" in my first astro images (1.2m FL on EQ3), one such example is here:

Unfortunately, quality tools cost, unless one is capable of making own thus saving some cash.
At this stage I'm happy with what I have, but would also like to expand into other areas such as visual astronomy and solar imaging, so it seems that collecting more astro rig will continue. Having said that, I reduced the amount of equipment about 6 months ago and now have only what I use.
