First of all you can get them on ebay for about 100 dollars. And yes a substitute would be going to the store or LFS and getting it. You`re better off spending the 100 dollars and make it at home.

water quality is one place you don't want to go cheap here..... Think of all the time and money you spend to get the tank running and after a few months your tank starts to grow this thick green hair algae and it takes over the tank.
Then you will be saying **** I should have listened to those guys....
and drinking the RO water is great.

The RO/DI unit I got from the US Based FilterDirect company on ebay (there's apparently a Canadian company trying to captialize on FD's success), is great. I would recommend it to anyone. I've had no problems with it and it continues to serve 0-1TDS water after way longer than I would have imagined!

I would consider that 100$ well spent. You don't need the storage tank either, for the purposes of filling a tank.

Most LFS will sell RO/DI for 1$/g but around here it is mixed to 1.019 rather than 1.025 I run my tank at.

Yes it does. Tap water varies from place to place but it will have ammonia , chlorine, chlomines, and heavy metals in most tap water. You can ask your county or city for a detailed study of your water. The study of my tap water in my county says on it not suitable for aquariums. As Seaham said it will cause nuisance algea problems and you`ll wish you had.

Ahhh...water. One of the most often overlooked componets of starting a new tank. Funny, since this is what goes IN the new tank. I cannot underestimate the importance of using a high quality water in your tank. RO/DI water will greatly reduce the amount of chemicals, heavy metals and TDS you introduce into your tank. To get started, you can certainy buy your water from the LFS. This will help save the start-up costs. However, for long term ease, you should really look into a RO/DI system for your home. There are many inexpensive models out there as Mike mentioned. I use a unit from www.thefilterguys.biz and am very happy with it.

Ohh...BTW...did I mention just how important water is???

That must be for SW instead of FW. FW should only run you about 50 cents a gal. As far as the filter goes...look for a at least a four stage unit and make sure it has a DI membrane and DI resin stage. A two stage will just not give you what you need.
