Have the opportunity to buy an entry-level mountain bike. Main use will likely be around town biking (to and from the tennis courts), and some light moutain trails (dirt and rock) as well as some paved trails.

So the questions:

1. Hardtail vs. dual shock - pros and cons of both

2. Brands: Kent vs. Cycle Force Group. I believe both are pretty low-end brands, but which has better quality? Specifically, I'm looking at the following bikes:
Kent Shogun Rock - dual shock, 26" 21 speed (Shimano gears)
Kent Shogun Trail Blaster - hardtail, 26" 18 speed (Shimano gears)
Kent Shogun Shockwave -
Cycle Force Group Mantis Eagle -- hardtail, 26" 18 speed

3. Accessories: helmet, gloves, water bottle, pump. anything else I should consider?

These are pretty much my only choices. I know there are better brands out there, but this is what I have to work with.

Thoughts?
