I need help making a supplies order

[Tikva]

I am plotting an order for things I need for caring for my orchids (not quite as much fun as plotting an orchid order!)
I am thinking of getting clear plastic containers all matching so things are neater.
I am having such trouble finding potting medium I like locally. Everything is too big or too gritty small - toward the end it's all muddy and I hate wasting.
I've gotten a few plants (Paphs) with coconut husks and what looks like sponge pieces....
I would like a medium that works sort of universally for any orchids I own and I'm enjoying trying ANY different orchids I come across.... maybe a mix that works for most if not all orchids - and whatever else is needed to add to the mix for certain orchids. Like sponge, charcoal......
Could anyone tell me what basic things might work for me?
I also really want to go S/H but it scares me!!!! I know Ray is the S/H expert and I've been reading his message board. LOVE seeing the pictures! We travel a lot and I think S/H would work great for me IF I get the money and the guts to try...
Thanks all!
