Thanks guys. He was asking about connecting his keyboard to his mac so he is investigating Marc's idea. But I suspect simplicity will win out so I'll point him at the Behringer mic too.
Thanks again

If he is looking to connect a keyboard too, he is highly likely to want to connect other items in the future as well. He should definitely be looking at an audio interface instead of a USB mic.
Unlike a traditional studio microphone, USB mic's have to have special electronics built in to allow an analogue signal (vocal) to be converted into a digital signal. This is called an analogue-to-digital converter (A/D). Some models also sport a digital-to-analogue (D/A) converter to allow the digital signal coming out of the computer to be monitored through a headphone socket built into the microphone itself. To keep costs down, USB mic's are likely to have inferior quality A/D and D/A circuitry, amongst other components, which is one of the reasons I personally would always opt for a dedicated mic + audio interface.
Another thing to consider is that the headphone amplifier build into the Tascam (and almost all other dedicated audio interfaces) will be far superior to the one on the Mac (this is true of practically all built-in headphone sockets on computers). The Tascam will therefore provide a more accurate representation of what is being recorded and what has already been recorded.
I should point out that Behringher have a somewhat sketchy reputation in pro audio circles, although later products are receiving more favourable press.
By the way, that T-bone microphone I linked to is manufactured for Thomann.de. and the range have a good reputation for the low price. They are as far as I know Europe's largest pro audio and musical instrument retailer and I have bought £1000's worth of products from them over the years (also from DV247, who I have no complaints about). You also get a three year warranty on any product you purchase from them, which I have used in the past and the service was A1.
Hope this helps.
