can you provide a pic of this small crack?

Many rims will show a tiny crack where they are joined, this is normal (most of the time anyway).

IMO it's better to have a rear wheel fail than a front

That is indeed where the rim is joined together, though in your case it is separating.

I'd start saving some monies for a replacement.

If you want to learn how to build your own wheel, here's a cheap rim (make sure you match the amount of holes in the rim to how many holes you have in your hub). I've had good luck with Alex rims.

Then figure out the spoke length you'll need, there are several calculators on the internet, or you can have a shop help you. You can find spokes here, but remember, you need to find the correct length before you order.

follow Sheldon Browns how-to for wheel building.

Wheel building takes time and patience, the most difficult part is getting the correct tension throughout the wheel.

It is very likely building your own wheel will end up costing more than a low-end off the shelf wheel, but you'll have the knowledge, and it is oh-so satisfying to build your own wheels!

It is indeed satisfying to build up a wheel. I didn't even take the time to true it because it's a junk wheel that I'm not going to ride, but it was fun and I'm glad I did it.

Gecko and evul9, a freewheel threads onto a freewheel hub like most older and a few newer bikes have. A driver is on a cassette hub. It it actually in the hub, with it's own bearings, pawls, etc. They allow you to run smaller drivetrains for weight savings and just the fact that it is out of the way more. They tend to last a long time with maintenance every once in awhile.
