Or you could simply buy one fully-assembled (there are both kit prices and assembled prices available for WD gear) and let someone else worry about such things, although granted it wouldn't be as much fun!

Even the fully-assembled prices of WD kits still represent excellent value for money compared to commercial items, which in many cases will not offer anything like the same sound-per-pound value or overall performance.

Either way, like Shane says, go for it!
