Yes, if you are not familiar with soldering then it would be worth the money to buy it pre-assembled. I used to work in component level electronic troubleshooting and so I had to solder a lot. Its not hard but if you have not done it before chances are high you will kill a component like a transistor or IC chip. Resistors, capacitors and such are a bit more resilient but you have to watch what you are doing with the solid state devices.
