Recommend a Tea Infuser

Due to the fact that coffee and I just don't get along, I've taken up tea drinking. Having bought some loose leaf tea from Adagio and making my own tea bags, I'm ready to invest into a nice quality infuser. It doesn't have to be anything fancy or overly expensive, but ideally it would need to be easy to clean and workplace friendly. I'm not sure if I want something like the IngenuiTEA or something a bit simpler like the Swiss Gold Tea Filter. I usually only drink a cup of tea at a time, so something that makes several cups isn't entirely necessary.
