It is important to know that filters don't improve the image wholesale- they just bring out details that are otherwise lost, mostly due to "irradiation"; that is, the tendency for low-contrast details to bleed into one another. If you are expecting something spectacular when using a filter, you will probably be disappointed. There have been times when details invisible with no filter have become obvious with it- but much of the rest of the planet actually suffers. That's the point-removing colors that would otherwise mask a particular detail. Filters are for the details only, not a general enhancer. I use Orion's color filters, not the cheapest on the market, but hardly "top-dollar" either. Brent, one of these days let's get together, maybe I can change your mind on filters. BTW, as our eyes age, our corneas tend to yellow (that's why old ladies sometimes have blue hair- it doesn't look blue to them, but silver) so we eventually get a filter FREE!

My experience is a bit different than most. I find filters degrade the seeing unless you have paid top dollar for them. My 8" (refractor) has a minus violet filter in it. I don't use anything elso, because they seem to confuste the image too much.
