Canon 70-200 f/2.8L IS and Canon 300mm f/4L IS possible sale/trade

Anyone interested in like a like-new Canon 70-200 f/2.8L IS or 300 f/4? I'm considering selling to consolidate my kit since I don't use either lens nearly as much as I'd like to. Ideally I'm looking to either sell or trade them for a 24-105 and 100-400.

Is the 70-200 the MkI or MkII? I'm in the market for a 70-200 but haven't decided whether to go with the I or II yet.

It's the MKI.

it was the MK-I....you can't go wrong with either. I ended up trading in the 70-200 and I'm keeping the 300.
