I just bought a 750GB and two 1TB units by Western Digital at Best Buy. Bought the 750 for I think $115 and then the 1TB mods showed up for the same price, which was a screaming deal. Very simple and I love it. Copied approx. 95,000 songs to each with no problemos.
*and you mentioned you just wanted to do the bare minimum... I would find the best deal you can ($/storage) that you can get and go with it. Yeah, maybe you'll be able to buy 2TB for the same price as 1TB within 3 yrs, but just go for the gold now.
