Well, as always, the price range will determine the quality of your purchases, and in recording equipment, it's not very forgiving. So depending on your needs and how high of a quality recording you want to make (or will want to in the future) will have all the say in what you buy.
Both of those would definitely do the trick. I, however, would never spend $150 (or anything, for that matter) on anything from Behringer. If I were you, I would go for the pack with the Alesis board. The only thing I would think of is to buy the pack piece by piece so that you could get a regular mic stand (probably with a boom) instead of the desk stand. This will help if you want to record an acoustic guitar, or anything besides your voice really.
Obviously you could spend a fortune, but when I took a good look at those links, the stuff looks like a pretty good starter pack. I'm always skeptical of those "Podcast Starter Kit!!!" packages because of all the crap in them. Those look pretty good, though.
