I have the
iLuv i177 for my bedroom. It's an alarm clock/radio/iPod deal for about $90. The sound quality is actually very impressive for the size, and I LOVE the alarm clock feature. It's easy to use and has more iPod control buttons on the top than the iHome H5. I've heard the Bose sounddock and wasn't particularly impressed, especially because of the price. I personally think the iLuv combines fuctionality and good sound quality with a nice price point (plus I got it for Christmas last year, so I didn't have to pay for it

)
If you need travel functionality, the Creative thing might be the way to go - the only real way to find out is to go to a place like Best Buy that has a lot of stuff on display, and check it out for yourself. Also try epinions.com for reviews of different products.
iHome and iLuv both make travel iPod speaker/charger systems:
iHome's portable stuff
iLuv's portable boombox
JLC also has some neat looking stuff. I'm pretty sure Fry's also tends to put their iPod speaker systems on display, if you need a way to try out the different options. Target sells a number of options, too.
