I've also had problems with The Big Ceramics store. Ordering stuff and not finding out it was out of stock til only half of my package arrives. Bummer. I order supplies through The Ceramic Shop now, they're pretty good people. Its crazy to think I can place an order with shipping way cheaper from a shop in Pennsylvania than ordering from a supplier in my own state (Trinity ceramics).
I have one of those Speedball Clay Boss wheels. Its held up alright for the most part. I've used it everyday now for 6 years doing production ware and only needed to changed out the ball bearings about 2 years ago which was super easy.
Tupperware containers of glaze and slip, vintage mustard jar packed with brushes, trays of tools for throwing/trimming. Studio isn't sectioned off for different things but everything is in reach by the wheel.
Try rolling your coils on another slab of clay. It might seem weird but I found it to keep your clay really plastic when just adding more water and re-kneading makes it tired feeling and more likely to crack.
