You really don't need as much special equipment as you might think. Here are some videos that I have found to be very clear and simple that show you how to make miso soup, sushi rice, and two kinds of sushi rolls using the specially prepared sushi rice.
To make the items below, the only thing you really NEED to buy that you probably don't already have (besides the ingredients) is the bamboo rolling mat (sudare) - which costs about $1.50-2.00 either online or at an asian specialty store. You can use any type of bowl to mix the sushi rice in (I used my wooden salad bowl, but even a glass mixing bowl would work) and use a wooden spoon instead of the shamoji/rice paddle. You can use anything to fan the rice, you've most likely already have knives, a tea towel, a colander, a chopping board, etc. You can use ramekins or other small bowls you already have for the dipping sauces (or they have some really cute melamine asian sauce bowls at Target for $0.99 - so that won't break the bank).
There are some sushi kits available online that have all the ingredients (except the seafood & vegetables) for $20-$25.00, but if you go to an asian specialty store you can get everything you need (and larger quantities) for the same price.
I've been having fun with my "adventures in sushi". It's not as hard or as expensive as you would think. I hope you consider giving it a try!
