Shopping for appliances

So we just got back from shopping for kitchen appliances (dishwasher, microwave, refer). We bought a new Kenmore (white) stove/oven the day after we moved in because the old green one that came with the house wasn't even worth opening.
We have decided that since the stove is white, we will buy all white appliances. Yes, it's not the trendy stainless steel, but this house will always be a "first time homebuyer" home, so why waste the money?
Anyway, it's crazy how much a dishwasher and over the range microwaves cost. Here's a breakdown.

Albert Lee
Whirlpool microwave: $329
GE microwave: $359
Whirlpool dishwasher: $509
GE dishwasher: $559

Sears:
GE microwave: $218! but smaller (1.5 cubic)
Whirlpool dishwasher: $509
Kenmore dishwasher: $399! yeah

So at Albert Lee, we'll get about $50 off each appliance because we still have a contractor's discount (even the business no longer exists....shh). Just a thought: Would it be worth it to get a business license for $15 with the state and open an account at these places? You'd save money at the paint store, Home Depot, etc. Seems like a good deal.

Now the Fridge:
Side by side freezer/fridge? or drawer in the bottom? Is a door in the bottom better? It seems like room on the inside is diminishing compared to the 1980s versions. I'm almost tempted to buy the old school freezer on top version. And how important is water? It seems most come with an ice maker or the option to install the kit, but water is a whole new ballgame. Seriously, what's wrong with tap water? or the Brita? Here in the G. NW we have some of the best tap water in the world. Plus, it's fluoride injected. Of course, the significant other wants all the bells and whistles. He insists we'll be taking the fridge with us if we move, so it's an investment. We'll see what "the new buyers" ask for in the purchase. Ugh, thank god we don't remodel kitchens for a living.
