I'm considering buying a docking station for my ipod touch 4g and I'd like some advice on what would be the best docking station to get.

So recommend away

No one gives a shit what trite garbage you write here.

In my opinion docking stations are a waste of money and time. I've had three different iPods and an iPhone, and really, the best thing is to buy some nice speakers and get a long minijack to minijack cable.

I've had two docking stations, but because every mp3-player gets outdated it's simply much nicer to have good speakers that you can keep for years to come. Also, if you buy a new iPod in a few years, maybe they've changed the shape slightly, so that it doesn't fit into the docking station. This has happened to me two times.

Oriolidae is right.

Buy yourself a set of speakers (and a subwoofer if you like your bass) so you can plug it into your laptop/pc/DVD player/game console whatever and you can play music from iPods and Mp3 players. I've got the Logitech Z323 speakers.
They're not that expensive (if you shop around. I got mine for much cheaper than they're priced). Cheaper than a decent docking station for sure and the sound quality is amazing. You don't even need a separate cable, you can just plug it straight into your iPod Touch. I would know because I have an iPod Touch too.
