Monopod vs Tripod

I have been contemplating between an investment in a combination monopod and tripod or purchase those two separately.

What I have come up with are pros and cons in purchasing a combination "pod" if you will.

Pros:

• Versatile
• Monopods most commonly used with video
• Monopod allow greater flexibility of the camera

Cons:

• Not the best to design to use with tripod
• Monopods are best used by themselves

Monopod Recommendations by sites:

1. Slik Monopod 350 priced at $33.00
2. 561 Monopod with 701 head priced at $250.00
