Depending on how many implements you want in your multi-tool, you can go very basic like the Leatherman Kick or all out like the Surge or Wave. Also, consider how much you're willing to spend. Do you want a quality multi-tool that will last or some cheap no-name thing that'll rust if you look at it cross-eyed?
I had a Gerber Suspension which retails just under $30 bucks at Lowes, Target, etc. It's an okay tool. The scissors are the basic Fiskars-type and it has a plain edge wharncliffe style blade that's not all that sharp and a serrated sheepsfoot blade that can be opened with one hand. It's made in China and like I said, it's an okay tool to have in the glove compartment or tool kit, but for me it's a little too bulky for it's small size. Also, there's a little bit of play in the pliers (which may be of concern to some) and some of the tools like the saw are just too short to be of any actual use. I wanted a compact multi-tool that wasn't heavy and had the basic tools the average joe really needs so I went with the Leatherman Blast. Yes, the Blast cost more than the Gerber Suspension, but it's fit/finish is much better and worth the $20 difference, in my opinion. Given the choice, I'd even get the Leatherman Kick over the Gerber Suspension.
